I recently read that in a series string of LEDs, it doesn't matter if the resistor is on the Vcc or Ground side. My ( self appointed ) logic deduced from this was that the resistor just had to be in the string somewhere. I have 15 LEDs, split into 5 series strings of 3 LEDs each. Vf = 3.2v Curre…

Did I kill the LEDs with an incorrect resistor position ?

Thanks RuggedCircuits

I'll put this experience down to "School Fees".

Just glad it wasn't something with my Arduino Mega connected to it.
