Octopus Electronic Bricks, you can use them to build electronics projects just as easy as piling bricks. By using Octopus electronic bricks, you may connect Arduino / Freaduino compatible boards easily with various digital, analog, and I2C/Uart interfaces. These breadboard-less firm connections are prepared to extensive modules like potentiometers, sensors, relays, servos ... even buttons, just plug and play.
This keyboard uses an analog input to read the five key states which saves IO resources for the Arduino. It can be used together with our I/O expansion boards to make an amazing interactive project.
