Hi all.
I want to use ULN 2803 to drive some relay. I've done with 2N2222 before and success.
My question:
Where do i connect the output of ULN 2803 to. Is it the output connect direct to the relay?
can somebody draw for me a simple schematic to connect the ULN 2808 to the relay.
I remember seeing the schematic somewhere in this forum but i can't get it.
Many thanks to you.
