Enviro:bit LEDs don't appear to light up

For some reason, the enviro:bit LEDs don’t seem to light up. Any idea why?

Is that with the test code?

What test code? Okay the forum is asking me to write more characters - I hope this is enough

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.
