i am working on project DIY project and facing a problem in power circuit.
i made a KIOSK mobile charging system
needed different powers sources for three different equipments
1)coin acceptor
2)CD room tray used as coin colletor
3)ardunio
4)L2983 IC for motors.
5)LCD for display
coin acceptor needs 12v and needs a common ground with ardunio to work . i made a seperate PCB for L2983 IC and it needs 9v to operate my motors of CD room.
PROBLEM: when turning on power without connecting Ardunio the pin of 5v gets 2.5v ?
if anyone can help me out how to solve this problem
GOUND is common for COIN acceptor & ardunio & L2983
