Dimmer Circuit. This circuit also works with other n channel mosfets as well. This electronic lamp dimmer circuit work for incandescent lamp not a fluorescent one.
Parts list for the above improved fan dimmer circuit. And a potentiometer vr 500k adjusts the sensitivity. To build an ac dimmer the zero crossing points the points where the wave changes its polarity are important.
The dimmer circuit is wired in series with the lamp you can say the dimmer circuits is installed in series with the lamp.
This led dimmer circuit is based on 555 timers. The objective of the circuit is to vary in intensity the brightness of the light bulb or fan speed by using a fixed source. This electronic lighting dimmer circuit is used to control the lamp for arbitrary brightness. I will thank utsource for sponsoring.
