Dimmer With Touch Switch Without Arduino or any Microcontroller
This circuit is a Dimmer With Touch Switch Without Arduino or any Microcontroller.
I just using two ICs (LM324 and CA3130).
The output is a PWM signal and its duty cycle can be adjusted by two touch pads from 0% to 100%.
Interesting thing in this circuit that the duty cycle remains the same even after turns OFF and ON the supply voltage.
I explained it in my YouTube channel here: https://youtu.be/MMfsP2cXfSs
