Hello. I have a question. There is a circuit with 2 picaxe 20m2 which go to light several leds by 2 ULN2003. Totally, it'll be 14 leds. If, basically, there is only 1 power supply (let's say 24v) and it will be:
Power supply / LM7805 / picaxe 20m2 / ULN 2003 / and the same power supply to ULN2003. All this twice.
Is there any precautions to have for the pic's or ULN2003 when powering from the same source.
Thank you
