Hello,
I just finished my second cube, but now the leds do not light up.
If I measure the voltage on the leds, it’s pretty low (0,30V) and steady. So no fluctuations, which is strange.
Compared to my other (working) kit, the voltage is higher and fluctuating, which is normal as the lights are switched on and off.
The microcontoller seems to be working as I can download/upload animations.
I’m wondering what might be the problem.
Can you please give me some guidelines?
Thanks.
