Octopus Analog Rotation Brick OBARot

In stock

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 the breadboard-less firm connection are prepared to extensive modules like poteniometers, sensors, relays, servos even buttons, just plug and play. 

Octopus Analog Rotation Brick is arduino compatible and can be rotated up to 300-degree. It is based on the potentiometer. With the Arduino IO expansion board, in combination, it can be very easy to achieve position-dependent interaction with the rotating effect or produce MIDI instrument.
