This is still in the planning stage, but I am looking to dim a set of 4x ~40W light bulbs (110V AC) using a uC. I only need 4 or 5 different settings from off to full.
What is the best way to go about this? I'm assuming a horrible idea but one could use 4/5 separate relays with a different resistor to trim the power getting there. But I figure there is a easier/cheaper way?
Cheers.
