Hey guys,
I am back with another issue regarding this project. I was able to successfully re-create the led display that I was working on at the start of this thread using a solderless breadboard. I even went so far as to add a 2804 darlington so I could power some higher wattage bulbs...everything worked perfectly when running it from the breadboard. So, I wanted to get a PCB made of it and using Eagle I designed the boards. I had a set made and they don't work! When I hook the power up, I only get one LED that lights and stays on, no back and forth motion. I've been over and over these designs, comparing them to my breadboard and to me, everything looks the same. I did split the circuit over two boards as the enclosure I need to use isnt big enough for one board. Can anyone provide any insight as to where I go from here?
Thanks,
Kyle
Here are the boards. Also note that the 220 ohm resistors connected to the LEDS are not on these boards but they ARE part of the circuit. Also, for the pads marked LEDs, I am soldering wires to an led bar array that is mounted on the enclosure itself, not the circuit boards.
