#119599 - I add a resistor. Responding to: ???'s previous message |
That is very close to my desgin but I happed a serial in parrell out on one side and the ULN2803 on the sink side. I ended up putting about a 10 ohm resistor between the LEDS and the ULN2803. Seemed to even the current out for all the leds. But I am no expert just fumbling around in the dark. |
