    Wheel sensors. For accurate movement - straight lines and set angles, then wheel rotation sensors are a must. This addon pack comprises 2 wheel encoder discs to fit inside the main wheels, two IR reflectance sensors, a jumper block and 2 resistors. Software in both python and ScratchGPIO makes use of the 16 pulses per revolution to travel fixed distances etc.

  • McRoboFace - Add Emotion and Fun to your Electronic Creation (MCFACE)

    McRoboFace - Add Character to your Creations!


    We all like adding blinky LEDs to our electronics creations, whether it is a robot, weather station or something that reads and displays sensor data. Now with McRoboFace you can add emotions to everything at the same time as adding blinkies.

    All the 17 RGB LEDs are fully addressable and can be controlled by most processors in the field using standard "neopixel" code. This includes Raspberry Pi, Crumble, Arduino, ESP8266, micro:bit and Codebug.

    We also offer a diffuser kit to provide that softer look. Kit contains an acrylic diffuser, screws, nuts and spacers for mounting
