For some reason, the enviro:bit LEDs don’t seem to light up. Any idea why?
Is that with the test code?
You have to program your Micro-Bit to make the Enviro-Bit work.
I was assuming you had done that and were running something on the Microbit.
The test code I was referring to is here.
There are examples there on how to use the different sensors etc. And code to turn those LED’s on or off.
