I have a bulbdiall kit that Ive assembled and everything has gone without incedent, until it came to testing the red/hour PCB. Blue and Green both successfully mounted and tested, but I get nothing at all from the red in normal clock mode and testing/alignment mode. Ive ohmed out LED1-LED6, and 10 from the uC to the LEDs and its all fine, Ive tried to meter it while in alignment mode, and its seeming like the pins arent changing states. I was suspecting a damaged/zapped uC, and ordered a replacement pre-programmed uC, and the FTDI serial cable. Before I go though the hassle of desoldering the uC I tried the source code meant for arduino 1.0 software, but its still the same.

However, my own code to chase the LED's on the red ring runs completely fine, so hopefully that eliminated bad solder joints and a damaged uC as everything runs fine. At the moment the original uC is still on.

Any suggestions?

Have you gone back to the original firmware since getting the red ring to work correctly? It seems that if the hardware is working, then it must be OK.

Yep, the red was working without any hardware fixes, just my test code put on. Ive tried the code for arduino 1.0 compiled in arduino 1.0 of course, and the older beady2.pde compiled in arduino 0023, both exhibit the same problem, with nothing on the red.

I'll probably attempt swapping the uC since it cant be the resistors, traces or LEDs, perhaps its something more internal and not something as simple as a blown pin.

I have not tried the "1.0" version, so I'd recommend only using the "0023" version if there's software uncertainty.

I don't see how there could be a hardware error (in the IC) that causes the red LEDs to not light under one set of software, but not to work in the other. It doesn't really seem plausible.

Are the red LEDs lighting up brightly, and in the order that you would properly expect?
