Fermion: SHTC3 Temperature and Humidity Sensor
The SHTC3 digital humidity sensor from Sensirion builds on the success of the proven SHTC1 sensor and offers consistent high accuracy within the measuring range. The sensor covers a humidity measurement range of 0 to 100% RH and a temperature detection range of -40 Celsius to 125 Celsius with a typical accuracy of ±2% RH and ±0.2 Celsius. The board supply voltage of 3.3 Volt to 5 Volt and a current consumption below 0.15mA in low power mode make the SHTC3 perfectly suitable for mobile or wireless battery-driven applications.

ArduiNIX
The ArduiNIX is an Arduino compatible shield which plugs right onto the top of the Arduino UNO board. ArduiNIX takes care of stepping power from 9 VDC wall adapter power supply up to a maximum of approximately 250 VDC to drive any and all Nixie tubes. ArduiNIX also provides Multiplexed display for up to 80 elements by using 4 anode channels and 20 cathode channels. Multiplexing increases the life expectancy of your Nixie tube investment.
Not only does the ArduiNIX provide a Nixie tube platform for standard clock functions, but it is also user programmable, meaning if you can program it using the arduino environment, you can make it happen on your Nixie display. Take special care when working with the ArduiNIX. The ArduiNIX Shield operates at high voltages. Be careful when handling it while it’s powered up. Normally the Arduino is safe to handle, but when used in conjunction with the ArduiNIX, voltages in excess of 200 volts may be achieved. Use caution. An IN-17 x 8 display board, and 8 x Russian IN-17 Nixie tubes.

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.
