PeterH:
Are you using ordinary small low power LEDs? They don't draw much current at all so they will cause very little voltage drop. Unless you're trying to run wires over hundreds of yards I wouldn't have thought you would have any problems. And if you do run the lines so far that voltage loss is a problem, given that the resistance of the lines is known and constant, you can just subtract that resistance from your current limiting resistors for the LEDs.
Thank you!
It makes perfect sense. I am using 4 ordinary 5mm LEDs.
We just discussed my first LED, which will tell me about Servo's actions.
My second LED will tell me when the effect pedal is ON.
I intend to connect it according to diagram below.
I will use same power supply both for the pedal and Arduino ( 9V DC)
IS THIS SAFE. Will it work?
