Here is the circuit on the breadboard:
what happens is all the digits "sort of" light up as soon as I supply the HV to it. You can still see it cycling through the digits like the test program I wrote is telling it too, but they seem to all be getting a little power regardless. I unplugged all the wires from the microcontroller and it still lights up most of the digits.
Is it possible that its simply not going to be happy (and work) on a breadboard with voltages of 170-190v? I was able to test it before on a breadboard with a couple of button switches and I could manually light up individual digits flawlessly that way. but the time I did that I used a different breadboard and the IN4 was connected by leads instead of being plugged into the BB itself.
Thanks!
