So I want to build a circuit that can control the intensity of a light bulb (powered by 220V AC, 60 Hz) through the output voltage of Arduino.
I know I must use Triac but the question is, is the output voltage/current of Arduino good enough to control the Triac current such that I can get different levels of light intensity?
The block diagram of the whole system is given below, the whole purpose is to control the intensity of light through the output voltage of Arduino only, I don't need any kind of light sensor or anything else...
[Arduino] --> [Light dimmer circuit] --> [light bulb]
I'm honestly new to this Triac thing and don't want to blow up things, so I need some guidance from experts like you :)
