Stamp Controlled Dimmer Switch

Hi Folks:

I want to use·an output from·a BS-2 set-up·as a·PWM·output which will·then produce·a variable voltage output. I would like to run this output into a dimmer switch to control·an incandescent bulb.

So far·I have found lots of·dimmer switch circuits but all of them have a potentiometer wired as a rheostat on the 120V line.

Anyone have any ideas on how to interface the two circuits without a lot of heartburn or parts?

Thanks in advance for the information.

Gerry Shand·

    I think the best appoach would be to replace the mechanical pot with a digital pot -- but I'd put optocoupling between the digital pot and the BASIC Stamp.
