SUMO:BIT - Sumo Robot Expansion Board for micro:bit

Want to participate in a Sumo robot competitions but you’re a complete beginner? Or want to try controlling a Sumo robot using a micro:bit mainboard? SUMO:BIT is here to the rescue!

Program your SUMO:BIT with Microsoft MakeCode Editor graphical programming interface. Just install SUMO:BIT MakeCode Extension and you may start to code your projects. If you’re a beginner, you can start with the block programming mode; simply drag, drop & snap the coding blocks together. For more advanced users, you can easily switch into JavaScript or Python mode on MakeCode Editor for text-based programming.
