HC-SR04 Ultrasonic Sensor

This is the HC-SR04 ultrasonic distance sensor. This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit.

There are only four pins that you need to worry about on the HC-SR04: VCC (Power), Trig (Trigger), Echo (Receive), and GND (Ground). You will find this sensor very easy to set up and use for your next range-finding project. This sensor has additional control circuitry that can prevent inconsistent “bouncy” data depending on the application.

MicroSD Card Breakout Board+

Not just a simple breakout board, this microSD adapter goes the extra mile – designed for ease of use.

  • -Onboard 5v->3v regulator provides 150mA for power-hungry cards
  • -3v level shifting means you can use this with ease on either 3v or 5v systems
  • -Uses a proper level shifting chip, not resistors: less problems, and faster read/write access
  • -Use 3 or 4 digital pins to read and write 2Gb+ of storage
  • -Activity LED lights up when the SD card is being read or written
  • -Push-push socket with card slightly over the edge of the PCB so its easy to insert and remove
  • -Comes with 0.1″ header so you can get it on a breadboard or use wires

To use with an Arduino, connect GND to ground, 5V to 5V, CLK to pin 13, DO to pin 12, DI to pin 11, and CS to pin 10.

ChronoDot – Ultra-Precise Real Time Clock – v2.1

The ChronoDot RTC is an extremely accurate real time clock module, based on the DS3231 temperature compensated RTC. It includes a CR1632 battery, which should last at least 8 years if the I2C interface is only used while the device has 5V power available. No external crystal or tuning capacitors are required.

The top side of the Chronodot now features a battery holder for 16mm 3V lithium coin cells. It pairs particularly well with CR1632 batteries. The DS3231 has an internal crystal and a switched bank of tuning capacitors. The temperature of the crystal is continously monitored, and the capacitors are adjusted to maintain a stable frequency. Other RTC solutions may drift minutes per month, especially in extreme temperature ranges…the ChronoDot will drift less than a minute per year. This makes the ChronoDot very well suited for time critical applications that cannot be regularly synchronized to an external clock.

RGB LCD Shield 16×2 Character Negative Display

With this in mind, we wanted to make it easier for people to get these LCD into their projects so we devised a shield that lets you control a 16×2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the Arduino. The shield is designed for Arduinos Uno. It uses the I2C pins at Analog 4 and Analog 5.

At this time, the library and shield can control the RGB backlight of our character LCDs by turning each LED on or off. This means you can display the following colors: Red, Yellow, Green, Teal, Blue, Violet, White and all off. This shield is perfect for when you want to build a stand-alone project with its own user interface. The 4 directional buttons plus select button allows basic control without having to attach a bulky computer.

Adjusting Contrast

The shield uses a character LCD with an external contrast potentiometer. The first time you use it, adjust the potentiometer in the bottom right until you see the text clearly.

Adafruit PowerBoost 500 Shield – Rechargeable 5V Power Shield

What’s a project if it’s trapped on your desk? Now you can take your Arduino anywhere you wish with the PowerBoost shield. This stackable shield goes onto your Arduino and provides a slim rechargeable power pack, with a built in battery charger as well as DC/DC booster.

Compatible with Arduino Uno basically any Arduino-pinout-shaped Arduino as only the GND and 5V pins are used. You can stack shields on top, or stack the PowerBoost on top. The PowerBoost shield can run off of any Lithium Ion or Lithium Polymer battery but we suggest our 2000mAh capacity batteries, both of which fits very nicely in the empty space of the shield. Plug in the battery and recharge it via the microUSB jack. When you’re ready to go, just unplug the Arduino from USB or the wall adapter and it will automatically switch over to shield power. Use only Lipoly batteries with protection circuitry.

The onboard boost converter can provide at least 500mA current, and can peak at 1A. There’s an onboard fuse to protect against higher current draws which could damage the boost converter or battery. The boost converter can be damaged by high current spikes and is not recommended for driving motors or robots where the stall current can cause high current spikes. It will let you turn the shield and Arduino power on/off.

Lithium Ion Battery – 3.7v 2000mAh

Lithium ion polymer batteries are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 2000mAh. If you need a larger battery. The batteries come pre-attached with a genuine 2-pin JST-PH connector as shown and include the necessary protection circuitry. Because they have a genuine JST connector, not a knock-off, the cable wont snag or get stuck in a matching JST jack, they click in and out smoothly.

ProtoScrewShield

The ScrewShield extends all pins of the Arduino out to 3.5 mm pitch screw terminals. It also has a lot of the utility provided by Arduino Protoshield, including: a large prototyping space of both connected and unconnected 0.1 inch spaced through-holes, a couple 5V and GND busses, a reset button, general use push button, and a 5 mm yellow LED. This product includes all the parts shown and comes in kit form and must be soldered together by the end user.

Fio v3 – ATmega32U4

The Fio v3 is a new spin on the Arduino Fio hardware powered by the ATmega32U4.Not only is it small and LiPo-ready, it’s a very capable XBee-ready development board. The JST-connector and 3.3v system voltage make this a great development tool for portable devices, simply plug in a Li-Poly battery and you’re ready to go. Wireless sensor networks and communication are made easy by the on-board XBee socket.

The ATmega32U4, running at 8MHz, makes it possible for you to use the on-board USB jack not only to charge a connected Li-Poly battery but to actually program the device. Because this board uses a similar bootloader to the one on the Pro Micro, you will need to download and install the special software driver below. There’s also a board definition add-on for the Arduino IDE which will add support for this board.

Music Acoustics

Music acoustics is a multidisciplinary field that combines knowledge from physics, psychophysics, physiology, and signal processing among other disciplines. As a branch of acoustics, it is concerned with researching and describing the physics of music, how sounds are employed to make music. Examples of areas of study are the function human voice (the physics of speech), computer analysis, and in the clinical.

White Noise

White Noise can be used by all audiences in a variety of ways throughout our daily lives. Whether you’re trying to work, study, relax, or even sleep. Offices can be either too quiet or too noisy. White noise makes it impossible to concentrate. Sound affects many areas of the brain and has an undeniable effect on the body. A good way to test if a particular sound is relaxing to you is to check your pulse, if it slows down, then you have found the sound that is calming you. Keep listening to it and you will relax, reaching a state of increased calmness and reducing your levels of anxiety, stress, or anger.

Wave Packet

In physics, a wave packet is a short burst of localized wave action that travels as a unit. A wave packet can be analyzed into, or can be synthesized from, an infinite set of component sinusoidal waves of different wavenumbers, with phases and amplitudes such that they interfere constructively only over a small region of space, and destructively elsewhere.Each component wave function, and hence the wave packet, are solutions of a wave equation. Depending on the wave equation, the wave packet’s profile may remain constant or it may change while propagating.

White Noise

Thus, random signals are considered “white noise” if they are observed to have a flat spectrum over the range of frequencies that are relevant to the context. For an audio signal, the relevant range is the band of audible sound frequencies (between 20 and 20,000 Hz). Such a signal is heard by the human ear as a hissing sound. In music and acoustics, the term “white noise” may be used for any signal that has a similar hissing sound. It is sometimes used analogously in nontechnical contexts to mean “random talk without meaningful contents”.
