HUSK PÅ AT DU SANDSYNLIGVIS BRÆNDER MODULET AF HVIS DU:

A) FORBINDER MODULETS DATA PINS TIL 3.3V ELLER 5V POWER PIN

B) FORBINDER V+ PÅ ET 3.3V MODUL TIL ARDUINO & ESP32 5V POWER PIN

- på MicroBit findes kun 3.3V power pin.

Hvis projektet bliver større, da er det måske på tide at finde en single-board computer eller en større microcontroller.
