I am considering a small lighting dimming project although at night the power to the whole circuit will be cut off. Is there a way to store values (specifically PWM levels for dimming) and have the lights return to the specified level of dimming automatically when the circuit powers on in the mornin…

This is impractical as will have multiple arduinos controlling seperate displays
