Is it possible to build an automatic light dimmer using an Arduino? I'm interested in adjusting the brightness of a light based on ambient light levels using a sensor like an LDR.
What components would be required, and how would the dimming be controlled, especially for an AC light? Are there any safety considerations I should know when dealing with AC dimming?
Any guidance or example circuits would be helpful.
