Project #7: RGB LCD Shield – Bi-Color LED – Mk09
Bi-Color LED
Bi-color LEDs contain two different LED emitters in one case. There are two types of these. One type consists of two dies connected to the same two leads antiparallel to each other. Current flow in one direction emits one color, and current in the opposite direction emits the other color. The other type consists of two dies with separate leads for both dies and another lead for common anode or cathode so that they can be controlled independently. The most common bi-color combination is red/traditional green, however, other available combinations include amber/traditional green, red/pure green, red/blue, and blue/pure green.
Super Bright BiPolar LEDs
Package of 12 super bright Red/Green jumbo T1 3/4 5mm LEDs. These have a diffused frosted lens and 3 long leads. Prime 100% perfect and bright. CODE 7: 100% Prime Parts. Stock # GP55

Project #7: RGB LCD Shield – Rotary Switch – Mk08
Rotary Switch – 10 Position
This is a single pole, 10 position rotary switch able to select up to 10 different states in a durable package. Unlike our other rotary switch, this model is much more robust and capable of handling larger currents and voltages.
With a max voltage rating of 125VAC at 0.3A and a dielectric strength of 250VAC for 1 minute this is a serious little rotary switch capable of working with some of your bigger projects. Though this switch requires you to use 11 pins and is not breadboard friendly we do offer a breakout board (found in the Recommended Products section below) to provide easier access to its capabilities.
1 x Rotary Switch – 10 Position
1 x Hex Nut
2 x Washer
Rating: 0.3A/125VAC
Contact Resistance: 50M Ohm max
Insulation Resistance: 100M Ohm @ 500VDC min
Dielectric Strength: 250VAC for 1 minute
Rotation torque: 1.0+0.5KG/cm
Shaft: 3/8″
Rotary Switch Breakout
This is the SparkFun Rotary Switch Breakout, a very simple board designed to easily provide you access to each pin on our 10-position rotary switches. This breakout allows you to easily add a rotary switch to your next project without having to worry about attaching its unique footprint to a custom board or solderless breadboard. All you need to do is solder the 10-position rotary switch into the breakout (using the silkscreen on the board as a guide) and each pin will become available for breadboard or hookup wire compatibility.
Each one of these boards breaks out the common ( C ), 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 positions on the board into 0.1″ spaced pins.
NeoPixel Stick – 8 x 5050 RGB LED
Make your own little LED strip arrangement with this stick of NeoPixel LEDs. We crammed 8 of the tiny 5050 (5mm x 5mm) smart RGB LEDs onto a PCB with mounting holes and a chainable design. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC (4-7V works) and you’re ready to rock.

Propaganda Electronics
Electronics
Electronics has been linked to by thousands of schools and universities, professional associations and research organizations, reference sources and other information authorities, newspapers, magazines and other news services, and increasingly bloggers and social networking sites such as Facebook, Twitter, Google+, and LinkedIn. Electronics enjoys high rankings with popular web search engines such as Google and Yahoo for hundreds of electronically important keywords, including the word “electronics” for which the site comes up in typically the top three search results.
Propaganda
Propaganda is information that is not objective and is used primarily to influence an audience and further an agenda, often by presenting facts selectively to encourage a particular synthesis or perception, or using loaded language to produce an emotional rather than a rational response to the information that is presented. Propaganda is often associated with material prepared by governments, but activist groups, companies and the media can also produce propaganda.
In the twentieth century, the term propaganda has been associated with a manipulative approach, but propaganda historically was a neutral descriptive term. A wide range of materials and media are used for conveying propaganda messages, which changed as new technologies were invented, including paintings, cartoons, posters, pamphlets, films, radio shows, TV shows, and websites.
Advertising
Propaganda shares techniques with advertising and public relations, each of which can be thought of as propaganda that promotes a commercial product or shapes the perception of an organization, person, or brand.
Journalistic theory generally holds that news items should be objective, giving the reader an accurate background and analysis of the subject at hand. On the other hand, advertisements evolved from the traditional commercial advertisements to include also a new type in the form of paid articles or broadcasts disguised as news. These generally present an issue in a very subjective and often misleading light, primarily meant to persuade rather than inform. Normally they use only subtle propaganda techniques and not the more obvious ones used in traditional commercial advertisements.
If the reader believes that a paid advertisement is in fact a news item, the message the advertiser is trying to communicate will be more easily “believed” or “internalized”. Such advertisements are considered obvious examples of “covert” propaganda because they take on the appearance of objective information rather than the appearance of propaganda, which is misleading. Federal law specifically mandates that any advertisement appearing in the format of a news item must state that the item is in fact a paid advertisement.
Techniques
Common media for transmitting propaganda messages include news reports, government reports, historical revision, junk science, books, leaflets, movies, radio, television, and posters. Some propaganda campaigns follow a strategic transmission pattern to indoctrinate the target group. This may begin with a simple transmission, such as a leaflet or advertisement dropped from a plane or an advertisement.
Generally these messages will contain directions on how to obtain more information, via a web site, hot line, radio program, etc. (as it is seen also for selling purposes among other goals). The strategy intends to initiate the individual from information recipient to information seeker through reinforcement, and then from information seeker to opinion leader through indoctrination.
A number of techniques based in social psychological research are used to generate propaganda. Many of these same techniques can be found under logical fallacies, since propagandists use arguments that, while sometimes convincing, are not necessarily valid.
Some time has been spent analyzing the means by which the propaganda messages are transmitted. That work is important but it is clear that information dissemination strategies become propaganda strategies only when coupled with propagandistic messages. Identifying these messages is a necessary prerequisite to study the methods by which those messages are spread.
Identifying
1. Consider the source (to understand its mission and purpose)
2. Read beyond the headline (to understand the whole story)
3. Check the authors (to see if they are real and credible)
4. Assess the supporting sources (to ensure they support the claims)
5. Check the date of publication (to see if the story is relevant and up to date)
6. Review your own biases (to see if they are affecting your judgement)
7. Ask experts (to get confirmation from independent people with knowledge)
Fake Electronics
The counterfeit means to imitate something. Counterfeit products are fakes or unauthorized replicas of the real product. Counterfeit products are often produced with the intent to take advantage of the superior value of the imitated product. The word counterfeit frequently describes both pharmaceuticals, aviation and automobile parts, watches, electronics (both parts and finished products), software.
Counterfeit products tend to have fake have a reputation for being lower quality (sometimes not working at all) and may even include toxic elements such as lead. This has resulted in the deaths of hundreds of thousands of people, due to automobile and aviation accidents, poisoning, or ceasing to take essential compounds (e.g., in the case a person takes non-working medicine).
Well, here are several online portals offering best stuff on electronics. But you should bear in mind that all the providers are not safe and may be you will provide you best quality products but charge of the products are very high. And I will tell you the best websites where you can get the attire as per your taste, if you’re looking for cheaper purchases.
Think of all the popular hardware brands in technology right now. The Apple and Sony that have the distinct honor of being considered a luxury brand. Everyone wants one and anyone who’s anyone would buy and flaunt them to their peers, creating an appeal. Unfortunately, not everyone can afford them and that’s where knockoffs come to the rescue.
These knockoffs were made as a copy of the original, sometimes using the logo and design of the original. Sometimes they get it right and many might not notice. Often at times, they get it wrong. Very wrong, in fact, to the point of hilarity. Here of the most amusing knockoffs of popular tech brands that you may have seen.
From quirky gadgets to fab mobile phones, India, South Korea, Japan and China are famous for producing trend-setting technologies that often take years to find their way to the West. Turns out there are a number of websites selling ultra-cool Asian electronics internationally for you techies out there. We’ve created a list of what we think are some of the top Asian tech-selling sites.
Another wholesaler for quirky, cool fake electronics tech stuff, stocks mobile phones and laptops as well as less mainstream gadgets. Spy on neighbors with the digital surveillance pen featuring image capture and video recording. The extreme sports helmet camera will let you capture crazy want to show your friends.
Fake electronics is the infamous shopping site offering B2B sales. Businesses can connect directly with wholesalers and manufacturers in India, South Korea, Japan, China, Taiwan, Hong Kong, Malaysia or Singapore.

Project #7: RGB LCD Shield – Line Sensor Breakout – Mk07
Line Sensor Breakout – QRE1113 (Analog)
Description
This version of the QRE1113 breakout board features an easy-to-use analog output, which will vary depending on the amount of IR light reflected back to the sensor. This tiny board is perfect for line sensing applications and can be used in both 3.3V and 5V systems.
The board’s QRE1113 IR reflectance sensor is comprised of two parts – an IR emitting LED and an IR sensitive phototransistor. When you apply power to the VCC and GND pins the IR LED inside the sensor will illuminate. A 100 Ohm resistor is on-board and placed in series with the LED to limit current. A 10k Ohm resistor pulls the output pin high, but when the light from the LED is reflected back onto the phototransistor the output will begin to go lower. The more IR light sensed by the phototransistor, the lower the output voltage of the breakout board.
These sensors are widely used in line following robots – white surfaces reflect much more light than black, so, when directed towards a white surface, the voltage output will be lower than that on a black surface.
The power input and analog output pins are brought out to a 3-pin, 0.1″ pitch header. The board also has a single mounting hole if you want to screw the board onto something.
Features
* 5VDC operating voltage
* 25mA supply current
* Optimal sensing distance: 0.125″ (3mm)
* 0.30 x 0.55 “ (7.62 x 13.97 mm)
Common Reflectance Sensor
The QRE1113 is a common reflectance sensor often used in robotic line followers. The sensor works by shining an IR LED down and seeing how much of that light bounces back using a phototransistor. Because dark colors will bounce back less of the light, the sensor can be used to tell the difference between white and black areas. So an array of these can be used to help a robot determine where a dark line is on the ground so it can follow it. But they can also be used to determine proximity under an inch.
The an analog input on your microcontroller but still need an analog reading of how much light was reflected. It does this by allowing you to charge a capacitor on the board, and then timing how long it takes to discharge. The more light that is reflected, the less time it takes to discharge the capacitor. Hooking the QRE1113 to your Arduino is very simple. It just needs power (5V), ground, and an analog pin.

Project #7: RGB LCD Shield – Seven-Segment Display – Mk06
Seven-Segment Display
A seven-segment display (SSD), or seven-segment indicator, is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays.
Seven-segment displays are widely used in digital clocks, electronic meters, basic calculators, and other electronic devices that display numerical information.
Your basic 7-segment LED. Common anode. Two decimal points, but only the one on the right is wired. Digit height is 0.6″. Overall height is 1″.
Common Cathode
In a common-cathode display, the positive terminal of all the eight LEDs are connected together and then connected to iSeven2 and iSeven8. To turn on an individual segment, you ground one of the pins. The following diagram shows the internal structure of the common-cathode seven-segment display.
The internal structure of both types is nearly the same. The difference is the polarity of the LEDs and common terminal. In a common cathode seven-segment display, all seven LEDs plus a dot LED have the cathodes connected To use this display, we need to connect VIN to make the individual segments light up. The following diagram shows the internal structure of common-cathode seven-segment display.
If your Arduino application only needs to display numbers, consider using a seven-segment display. The severn-segment display has seven LEDs arranged in the shape of number eight. They are easy to use and cost effective. The picture below shows a typical seven-segment display.

Project #7: RGB LCD Shield – LED RGB – Mk05
LED RGB
LED RGB are tri-color LEDs with red, green, and blue emitters, in general using a four-wire connection with one common lead (anode or cathode). These LEDs can have either common positive leads in the case of a common anode LED, or common negative leads in the case of a common cathode LED. Others, however, have only two leads (positive and negative) and have a built-in electronic control unit.
LED RGB (Red-Green-Blue) are actually three LEDs in one! But that doesn’t mean it can only make three colors. Because red, green, and blue are the additive primary colors, you can control the intensity of each to create every color of the rainbow. Most RGB LEDs have four pins: one for each color, and a common pin. On some, the common pin is the anode, and on others, it’s the cathode.
Circuit Schematics (Common Cathode)
The cathode will be connected to the VIN and will be connected through 330 Ohms resistor. We will use PWM for simulating analog output which will provide different voltage levels to the LEDs so we can get the desired colors. We will use PWM for simulating analog output which will provide different voltage levels to the LEDs so we can get the desired colors.
Source Code
I will use the pins number 4, 3 and 2 and I will name them iRed, iGreen and iBlue. In the setup section we need to define them as outputs. At the bottom of the sketch we have this custom made function named setColor() which takes 3 different arguments red, green and blue. These arguments represents the brightness of the LEDs or the duty cycle of the PWM signal which is created using the analogWrite() function. These values can vary from 0 to 255 which represents 100 % duty cycle of the PWM signal or maximum LED brightness.
So now in the loop function we will make our program which will change the color of the LED each 2 second. In order to get red light on the LED we will call the setColor() function and set value of 255 for the iRed argument and 0 for the two others. Respectively we can get the two other basic colors, green and blue.

Project #7: RGB LCD Shield – IR Emitters and Detectors – Mk04
Infrared Emitters and Detectors
Side-looking Infrared Emitters and IR Detectors. These simple devices operate at 940nm and work well for generic IR systems including remote control and touch-less object sensing. Using a simple ADC on any microcontroller will allow variable readings to be collected from the detector. The emitter is driven up to 50mA with a current limiting resistor as with any LED device. The detect is a NPN transistor that is biased by incoming IR light.
Sold as a pair, with one Emitter and one Detector.
IR Emitter
Connect IR LED using a 270 ohm series resistor to the +5 supply (or to an Arduino pin if you want to switch the source on and off). Current draw is about 11 mA with a 270 ohm resistor. Current runs from anode to cathode. Flat on the case marks the cathode. To determine if the IR LED is the right way around.
IR Detector
A IR Detector is just like a regular transistor except the base lead is disabled or absent and light activates base current. The flat on the case marks the collector, the other lead is the emitter. Connect the collector to one end of a 10K ohm resistor and connect the other end of the resistor to a +5V supply (you can use the +5 pin on the Arduino). Connect the emitter to ground. The voltage should start out at +5V. When pointing the IR Detector, the voltage should drop down to near zero. To interface with the Arduino, make a second connection from the collector to an Arduino pin.

Project #9: Stepper – EasyDriver – Mk04
EasyDriver – Hook-Up
Once you have all the headers soldered on, it’s time to hook up the EasyDriver to your Arduino. Using the picture below, make all the necessary connections.
Note: The small stepper motor looks different than the one pictured. It should have a 4-pin connector on the end. This will be attached to the 4-pin male header facing upward. Because of the nature of this particular stepper, you can hook up the connector in either orientation, i.e. either the black wire on the left or the yellow wire on the left. It will work either way. If you are using a different motor, consult its documentation to find out which wires should go where.
IMPORTANT: Stepper motors require more power than can be supplied by the Arduino. In this example we will be powering the Uno with a 12V external supply. Notice that the power input (M+) on the EasyDriver is attached to the Vin pin on the Arduino. This will allow you to power both the Arduino and the motor with the same power supply.

Project #9: Stepper – EasyDriver – Mk03
Assembly
The simplest way to use the EasyDriver is to attach headers to it for easy insertion onto a breadboard. Alternatively, you could solder the wires straight to the board. These instructions will assume you are using the breadboard method.
The first step is to solder straight male headers to the EasyDriver. Very few of the actual pins on the EasyDriver will be used in this example. However, soldering headers on all the broken out pins is recommended to give the board more stability when attached to a breadboard. A simple method for this is to break off the desired amount of headers, place them in the breadboard in the appropriate locations, place the EasyDriver on top, and then solder all the connections.

The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). The EasyDriver requires a 6V to 30V supply to power the motor and can power any voltage of stepper motor. The EasyDriver has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and you’ve got precision motor control! EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors.
This EasyDriver V4.5 has been co-designed with Brian Schmalz. It provides much more flexibility and control over your stepper motor, when compared to older versions. The microstep select (MS1 and MS2) pins of the A3967 are broken out allowing adjustments to the microstepping resolution. The sleep and enable pins are also broken out for further control.
Note: Do not connect or disconnect a motor while the driver is energized. This will cause permanent damage to the A3967 IC.
Note: This product is a collaboration with Brian Schmalz. A portion of each sales goes back to them for product support and continued development.
Features
* A3967 Microstepping Driver
* MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)
* Compatible with 4, 6, and 8 wire stepper motors of any voltage
* Adjustable current control from 150mA/phase to 700mA/phase
* Power supply range from 6V to 30V. The higher the voltage, the higher the torque at high speeds
