An adjustable potentiometer can open up many interesting user interfaces. Turn the pot and the resistance changes. Connect VCC to an outer pin, GND to the other, and the center pin will have a voltage that varies from 0 to VCC depending...

The SparkFun BlackBerry Trackballer Breakout gives you easy access to a trackball which measures up, down, left, and right movements, clicks on the board, as well as adding a bit of flair to your project with four built-in LEDs. The...

This is the LilyPad Arduino Simple Board. It’s controlled by an ATmega328 with the Arduino bootloader. It has fewer pins than the LilyPad Arduino Main Board, a built in power supply socket, and an on/off switch. Any of our LiPo batteries...

The LilyPad SimpleSnap is a new, easy way to create e-textiles projects with LilyPad that are modular and can be disassembled or broken down, it’s also a great way to prototype! The SimpleSnap board is similar to the LilyPad Simple...

It’s blue! It’s skinny! It’s the Arduino Pro! SparkFun’s minimal design approach to Arduino. This is a 3.3V Arduino running the 8MHz bootloader. Because the system voltage for this board is lower than other Arduino development boards, it...

It’s blue! It’s skinny! It’s the Arduino Pro! SparkFun’s minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader in a super-sleek form factor that will fit easily into your next small project. Arduino Pro...

Two pin, compact surface mount connector. We really like the solid locking feeling and high current rating on these small connectors. We use these all the time as battery connectors.

This is a 2-pin, through-hole PH series JST connector. The pins are spaced by 2mm. We really like the solid locking feeling and high current rating on these small connectors. This connector will mate with all of our LiPo batteries.

A vibration motor! This itty-bitty, shaftless vibratory motor is perfect for non-audible indicators. Use in any number of applications to indicate to the wearer when a status has changed. All moving parts are protected within the...

Description: Do you make time to talk to your Arduino? Maybe you should! The EasyVR Shield 3.0 is a voice recognition shield for Arduino boards integrating an EasyVR module. It includes all of the features of the EasyVR module in a...

The Intel® Edison is an ultra small computing platform that will change the way you look at embedded electronics. Each Edison is packed with a huge amount of tech goodies into a tiny package while still providing the same robust strength...

This is a small voltage and current sense PCB. DC current is determined by measuring a voltage drop across a pair of parallel shunt resistors, then converted to a final analog voltage output by the TI INA-169. Voltage sense is...
