As another checking if there really is a change in the pulsing in the signal wire, w/ a circuit inbetween the signal wire (the wire that gives supposedly a pulse signal) to the arduino, i have connected a LED in between.
With or w/out this circuit in between THEY HAVE THE SAME RESULT.
the thing is as i turned on the coin slot and the arduino, as well as the LCD and all of them being connected, the LED in the circuit is continuously lit up. As I inserted the a coin it shows a change and blinks:
When P1.00 coin is inserted, it blinks once.
When P5.00 coin is inserted, it blinks 4 times.
When P10.00 coin is inserted, it blinks 8 times.
