2 coin acceptors, 1 bill acceptor, a bluetooth module and relay module attached to 5v bolt lock, is it possible to attached these to one arduino uno? I'm going to start my project right now but I have no idea if this is possible. I'm a newbie. Thanks in Advance
What hardware/software interface does the coin and bill acceptor use? Do you have the docs?
Start with smaller projects and work your way up. There are plenty of examples in the Arduino IDE (software development package) that teach you the language and more importantly, the special features of the Arduino.
Otherwise, expect endless frustration.
