I have recently acquired a Macqueen as a birthday present for my grandson and we were unable to get it to move. I checked the micro:bit by running microbit-troubleshoot.hex and the response was displayed “OK” .
This is the code that I uploaded to the micro:bit inserted in the Macqueen. The response was left light came on but there was no movement of the wheel.
Previous versions of the Macqueen had wires to connect the servos to the servo pins but not on this model that I received. The Java Script above mentions the servo pins and I’m wondering if the lack of wiring to the servo pins is the problem.
