Hello guys anyone help me my problem is how to isolate the stray signal of may coin slots
I have not inserted any coin but they have already count
Is the input to the coin counter floating at an unknown voltage or is it held at a known level by a pullup or pulldown resistor ?
Please post a schematic of your project showing clearly how its components are interconnected and powered

A wiring diagram and your code might be useful; please include all components and power/gnd and add the names of the components. Are you using pull-up / pull-down resistors on the signal lines from the coin acceptor?
I've moved your topic to the more generic hardware section of the forum.

Im not using resistor
So are you using the internal pull-up?
How difficult is it to post code and a wiring diagram?

It appears like a high impedance input is floating. We can say it is one of the pins on your Arduino and indicate your questions is answered. Without a decent schematic that will be my answer.
This OP is not new to the forum, never starts with supporting information or documentation, always has vague topics, eventually wanting premade code (or lines one at a time), eventually becoming 50-post (average) Stone Soup.
wait for the wiring diagram
