In this post I have explained a porch light circuit with programmable timer controller which enables the connected LEDs to light up or shut off after some delay, as preferred by the user, thus it’s not entirely dependent on the solar panel parameters. The idea was requested by “Unknown”. Technical Specifications It’d be neat if […]
