Using a 5V Attiny, I want to control the full brightness range on some 1.8V and 2.8V LEDs. If I set up two switching regulators leading to transistors and then PWM a transistor for each light, can I expect smooth variable output? Or is there a better solution?
They're part of a $15 switch, so I'm afraid to PWM at the full 5V. Thanks for reading!
