All of the RobotGeek I/O boards use a standard 3-pin connection. These three pins supply Ground (black cable), VCC (red cable), and Signal (white or yellow wire). These three pins allow us to connect a variety of digital input, digital output, and analog input boards easily to the arduino.
For attaching a single sensor to the Arduino, you can use a Squid Cable and Coupler Pin to hook up any of our sensors. For multiple sensors you can use our RobotGeek I/O boards with any of the shields or control boards listed below.
*These RobotGeek Sensors are electronically compatible with the 2/2/2 kit, but the connectors are not plug-and-play.
