Description
This project consists of an AC light dimmer for one or two incandescent light bulbs or dimmable LED bulbs, with mains AC voltage of 110 to 220 V, 50 or 60Hz, up to 400W, using the WiFi enabled microcontroller ESP-12E /F.
The Dimmer functionality is achieved using the phase control method, using a TRIAC for each bulb, varying the total power applied. This method works very well with incandescent light bulbs and with LED lamps that have the Dimmable specification.
