220V AC Voltage regulator, controlled with micro controller? Answered
I'm fairly new to Arduino (I'm actually using Netduino), and I have been puzzling with making a voltage regulator, for a 100W lightbulb. But my issue is, that I would like to control it digitally, with a micro controller - and not with the usual potentiometer.
Is there some kind of digital potentiometer I could use, or create?
Or better yet, instructables on doing something similar to this? I've been looking, but all seems to be manually operated, and most of them are for low voltage DC.
I'm pretty new to electronics as well, and I definitely would prefer, to NOT burn down the house.
Any advice, comments and links are much appreciated :)
