I need to control a bulb of 220V, with different intensity light levels. I've an Arduino Uno Board, which receives a variable voltage from a Light-to-voltage converter (TSL12S) (Like a photoresistance).
Depending of the received voltage in the Arduino board, I need to vary the light intensity of the bulb.
The output of the board is PWM, so I think that I need to connect to a DIMMER.
How to connect the PWM output to a Dimmer, and how to control the bulb with this? I've been looking for Dimmers in order to connect this, but all the dimmers that i've seen have a potentiometer to regulate this, and I need to regulate with the PWM output from Arduino.
