hello, ive been having trouble with our pcb layout for our light following robot. for some reason, only motor 2 works on the pcb layout, with motor 1 completely dead. here is the schematic diagram that we're trying to follow and the pcb layout we made:
schematic:
pcb layout:
the jumper wire was an improvisation because originally we didnt put a connection between battery negative to IC 2's pin 1. we've rechecked the connections over and over but we feel like there's nothing wrong with them and couldnt see the mistake (if there is). it also couldn't have been our components since they were all newly-bought and tested. im assuming that maybe theres something wrong with the resistors, the jumper thing wasnt a good fix, or that maybe we didn't properly follow the schematic design.
can anyone point out our mistake here? i'd really appreciate it. thanks in advance!
