PC Controlled Dimmer Circuit
8 channel mains dimmer
The heart of the dimmer is a ATTiny2313. the AVR performs three tasks: – It receives new data via the com port, – He receives pulses and the power of positive to negative goes and vice versa, this is called the zero crossing. – He makes 8 pulse-width modulated signal (PWM) with a frequency of 100 Hz. these signals are equal to the zero crossings from the mains.
The PWM signals control 8 optotriacs. These are optocouplers but with a built-in low power triac which can switch. In this project be MOC3021 optocoupler used. You can also add other optotriacs use as long as they have no zero-crossing detection, because working not if you want dim.
