I have a string of leds which I want to be able to fade in/out over a 30 min period. PWM seems to be the obvious answer. But looking through various posts and articles etc, I can’t find any reference to intergrating PWM over a specified time period. Has anyone tried this, can you give me a steer in the right direction.
Also I’m planning on a logic level MOSFET to control the 12v supply. Has anyone played with these?
