App note: Lamp dimmer using PIC12C508

Sunday, February 19th, 2012

Here is a reference design from Microchip describing how to built a Light dimmer with a PIC12C508 and a few discrete components. The circuit uses a simple zener voltage doper, to drop the voltage from mains to 5V required by the PIC. Watch out, there is live mains voltage involved....
