Hello.
I am a current student working on an electronics project. My professor has instructed us to go on the web and find a schematic on a digitally controlled light dimmer switch using a triac. After a few hours of searching I have found nothing that even remotely looks like what my professor is asking me to find. I was hoping someone on here would be able to direct me to where I can find such a thing.
What I know is that the circuit needs to contain a DAC, Optocoupler, and a triac. From what I understand the circuit is to be controlled by a bank of digital switches which feeds into a DAC to convert the digital signal into an analog signal. Then I am guessing that signal gets fed through an op amp then through an opto coupler which then is tied into a regular light dimming circuit.
If anyone knows anywhere where I can find more information on such a circuit I would be extremely grateful.
Thanks,
David
