User+Programmable+Automatic+Night+Light

In this project we developed user programmable automatic night light using Microchip's 8bit MCU – PIC12F675. In this design user may be able to program and store the time duration of the master light. Compared with other designs this circuit use transformerless power supply, and TRIAC to control the master light.

To get more information about transformerless power supply please refer the Microchip application note [|AN954], and ST application note [|AN438] for MCU and TRIAC interfacing.
