Im a bit new to this
I am using a picaxe 14M2
I have connect a 330 resisted and a LED down to ground on a PMW pin
I can control the brightness by adjusting the PMW no problem
but am struggling to under stand how much current is going to be pull though the chip
I only get about 2.5 volts out off the pin so it appears to be using around 9ma (I was expecting it to be near to 15ma)?
I am trying to work out the best way to add as many LED on 1 pin with out blowing up the chip
can anyone explain the best way to do this (at what point should I be look at using a driver circuit? (I really what to keep to the least amount of components possible)
