How can you make a simple light-dimming circuit?
To make a simple light-dimming circuit, use a TRIAC or a MOSFET along with a variable resistor or a potentiometer for control. Connect the light (like an incandescent bulb) in series with the TRIAC or MOSFET, and use the variable resistor to adjust the firing angle of the TRIAC or the gate voltage of the MOSFET, thereby controlling the brightness of the light.
