In combination with an Arduino IO expansion board it can be very easy to achieve position-dependent interaction with the rotating effect or produce MIDI instrument.
What are Octopus Electronic Bricks?
Pi Supply Octopus Electronic Bricks can be used to build electronics projects just as easy as piling bricks. You can also connect Arduino compatible boards easily with various digital, analog and I2C/Uart interfaces. The breadboardless connections let you connect expansion modules like potentiometers, sensors, relays, servos, buttons in a plug and play way.
