Hi!
I´ve got a power led (1W) circuit which I can control a led from 0% to 100% by a PWM control embebbed in the circuit, through a potentiometer.
I´d like to be able to choose some led intensities and have them pre-set by pressing a button (maybe one button to increase the intensity, and one to decrease) instead of a continuous variable potentiometer.
Is there any circuit for it? Any hints for where to look for it?
Thanks for reading!
