12V Light Control Switch

By Boris Landoni on August 4, 2020

Simple circuit able to automatically activate a load (lamps, etc.) when the the brightness in the room drops below a threshold that can be set as desired (adjustable via trimmer). The switch will return to the initial condition as soon as the brightness level reaches the preset level. It has relays with contact output (common, open and closed), status LED for power supply and relay activation.
