Description

The module, implemented with a PIC 16F877a, consists of 4 circuits, light sensors,a zero crossing detection circuit, the brightness system control and the serial communication circuit. The crossing detector circuit let us to synchronize the PIC with the AC network, detecting the zero crossing of the voltage. The brightness controller is implemented via software with a pulse that drives the triac through an optocoupler MOC3021. The source code is compiled by PIC C compiler.
