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 micro:bit / Arduino / Freaduino compatible boards easily with various digital, analog and I2C/Uart interfaces. These the breadboard-less firm connection are prepared to extensive modules like poteniometers, sensors, relays, servos ... even buttons, just plug and play.
This keyboard uses an analog input to read the five key state which saves IO resource for the Arduino. It can be used together with our I/O expansion boards to make amazing interactive project.
