How to build TRIAC Light Dimmer
October 12, 2010 - category: Light dimmerDescription
This little circuit can be used to dim lights up to about 350 watts. It uses a simple, standard TRIAC circuit that, in my expirience, generates very little heat. Please note that this circuit cannot be used with fluorescent lights.
Circuit diagram
Parts
- R1 50K Pot
- R2 15K 1/2W Resistor
