![]() ![]() ![]() ![]() Mini switch controlled with light using CD40106 Even common light so can control turning on / off switch. If modern must be controlling by Infrared light or remote control.Īs well as uses radio frequency to control turn on / off switch. The most basic way is to press the switch directly. The Operation of switch has several forms. Which use the inverter gate IC-40106 as main components in compare and controlled switches, and common phototransistors as sensors This is Simple light controller circuit that is controlled light-activate. Read first for beginners: How do transistor circuits work Simple phototransistor light controller circuit Other detail has a little and build easily. The equipment that use to replace such as Q1 = 2N2222 use other numbers can replace almost be finished request a kind NPN alike enough such as BC549 or BC337 or C1815 or C945 etc.įor oval should use 6V-9V sizes that are valuable the resistance within relay coil about 500ohm. The VR1 perform fine decorate the rapidity of the circuit. ![]()
