Hi,

Where can I find the circuit layout for the traffic-light simulator project?

Thanks, Brian

The comments in the code mark which pins each led should be wired to, but I didn't find a layout in the doc's I got with my nerdkit.

Hope this helps!

I noticed after running the simulator for a minute or so, the LCD starts to dim until I can no longer read it. I'm assumng this is because of too much current being drawn from the battery. I hooked up the LEDs as described in the source code but I think I should be using a resistor or something?

Forget the battery....find an old cell phone powersupply....many of them are switching and in the right voltage range...batteries are the bane of our existence.

I guess I could do that, but I think I did something wrong with the circuit's setup.
