I'm trying to hack an old traffic light, making the 3 incandescent AC bulbs independently controllable and, ideally, dimmable. My thought is to either have a series of buttons or a multi position switch to put the lights into different modes.
Modes could be:
- regular traffic light operation (green for awhile, then momentary yellow, then red for awhile, etc)
- dimmable sequence (red on then dim to yellow then dim to green, etc)
- dimmable random
- all on
- maybe somewhere down the road make them react to sound
This would all be pretty trivial if it weren't for the dimming part...
I found this discussion:http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1150063488
Which links to this kit:http://www.apogeekits.com/light_dimmer.htm
But at $32 per kit, and the fact that I'd need 3, and the fact that I'd have to assemble each kit, I'm leery...
I also found this discussion:http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1236998971/0#0
Which links to this board:http://ryanjmclaughlin.com/arduino/
But can't tell if that does what I need it to do.
I should probably add that I'm new to Arduinos but not to programming. I've been wanting to do an Arduino project forever, and this seems to fit the bill nicely.
Thanks gigantically for any help, and I'll keep this thread updated with source code and schematics as/if the project takes shape.
