Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Good evening all..!

Since I have never tried this before, I thought I would "ask the audience" and see what others might know abut this... (should be simple)

I want to control an LCD back light with PWM drive using a "slow averaged" value coming from an ambient light sensor of some kind... OK, maybe a simple CDS cell going into an analog pin and such... Does anyone have a "all ready proven" circuit that does the job..? It might be fun playing around with this, but, with so much other stuff on the list, I think I'd rather just hook it up and get on with this one...

Parts came in for the big G. 470 board and i think it's time for a little iron work this weekend... (sweet)...

Thanks Gent's..!!
