HELP!  I've been working on my senior project and find that I need
a light dimmer circuit that can control an incandescent(sp?) 120VAC
lamp from a 0-5V control signal.  I've tried several dimming circuits
and can't seem to find anything that works.  I've been using quadracs
(triac w/internal diac trigger) and find that I can't vary lamp
brightness much -- with a normal dimmer circuit (like the ones I see
in various books) I get on, 1/2 on, and off, which is unacceptable.
If anyone could e-mail some useful ideas to me, I'd really appreciate
it.  (Oh, and I need info ASAP, since it has to be working in a month!)
Thanks a million.....
