Build a Color-Sorting Robot with Just a Smartphone and Micro:Bit (Teachable Machine Tutorial)

*Micro:Bit Robotics - Video Course for Teachers* https://cardboard.lofirobot.com/courses/microbit-robotics-for-teachers/ *Printable Robot Designs* https://cardboard.lofirobot.com/product/printable-robot-designs-pdf/ Project info: https://cardboard.lofirobot.com/color-sorter/ *Teachable Miro:Bit APP* https://cardboard.lofirobot.com/teachable-microbit-app-info/ This color sorting machine is a part of a collection of PING PONG BALL CONTRAPTIONS which allow to build crazy factory lines to transport and sort colorful ping pong balls. These contraptions are a great project for a bigger workshop with large group of participants – my record was 100 participants at a time building a factory with 24 machines. Machine is operated with a Teachable Micro:Bit App that runs a machine learning model trained with Teachable Machine. The model aims to detect color of the ping pong ball in the machine cup. Colors detected by the app are sent over bluetooth to Micro:Bit which turns a servo motor to roll the ball either left or right.
