Decorative light Controller

Dimmer control is often used to change the brightness of the light with AC. Bidirectional thyristor(TRIAC) is used for controlling current. The circuit which controls a thyristor using a variable resister and a capacitor is common. The circuit introduced on this page is a circuit which controls a thyristor by software of PIC.
It is also possible to make control the electric bulb on a Christmas tree bright gradually and dark gradually. Blink control of various patterns can be performed.
