This is a 2 channel AC lamp fader.The project can apply where it needs to fade an Incandescent AC Bulbs.
Operation
This circuit will fade out two 230V AC bulbs accordingly which means when one bulb starts to fade from dim to full brightness the other bulb will fade from full brightness to dim at the same time.
Speed Adjust
To change the fading rate (speed) adjust the preset value at any time.
Time Limits
There are some time limits in this circuit because the whole time base is running under 50Hz frequency.
Minimum fade time from fully dim to fully bright = 2.5Seconds
Maximum fade time from fully dim to fully bright= 25Seconds
After power up the whole circuit affected by the AC mains. So be careful when powering the circuit.
