{"title":"Octopus Analog Rotation Brick OBARot","handle":"octopus-analog-rotation-brick-obarot","url":"/products/octopus-analog-rotation-brick-obarot","description":"   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.  The Freaduino Sensor Shield is the perfect shield to connect this senor to Arduino. Or Freaduino UNO which we had pre-stray Octopus Brick interface. Specification Power supply needs: 5V Interface type: Analog Pin Definition: S-Sigal V-VCC G-GND Wide detecting scope Fast response and High sensitivity 300 degree rotation sensor Size: 19x27mm Quick Start Hardware Connection Connect analog rotation brick to P0 port on OCTOPUS:BIT.   Programming Code You can see the whole program from the link here Result Rotate the knob on analog rotation brick in clockwise direction, then LEDs on micro:bit screen will be turned on gradually. Rotate the knob in anti-clockwise direction, then LEDs will be turned off one by one. Resources: Please visit the ElecFreaks wiki page for more info about this product.
