#186868 - ULN2003a Responding to: ???'s previous message |
Yes I agree entirely. The ULN2003a chip in the schematic's purpose is to drive both relays. Within this chip are flywheel diodes to 'take care' of the back emf from the relays however the problem still continues as I type this, so I'm still unable to resolve this. |
