Re: lamp dimmer

please specify the working of your circuit.... using what do you want to control your dimmer and other things......
 

Re: lamp dimmer

You can use a DAC and control its input thro' a digital circuit.The output of the DAC should be amplified and drived to the lamp.Thus by decreasing the digital input, You can make the light dimmer..
 

Re: lamp dimmer

You'll need a microcontroller, a triac, and a zerocross detector. Thats all. Check out microchip and atmel application notes. App. notes about motor phase control would describe the circuits more or less the same you need. Load would be lamp rather than a motor.
