Octopus Electronic Bricks! You can use them build electronics projects just as easy as piling bricks! By using Octopus electronic bricks, you may connect Arduino or compatible boards easily with various digital, analog and I2C/Uart interfaces. These breadboard-less firm connections includes an extensive collection of modules like potentiometers, sensors, relays, servos, and even buttons. Just plug and play!
A rotary or "shaft" encoder is an angular measuring device. It is used to precisely measure rotation of motors or to create wheel controllers (knobs) that can turn infinitely (with no end stop like a potentiometer has.) This Octopus brick can add this functionality to your project!
