An AutoStop mod project using an Arduino Nano

[Mcrowell75]

With the help of atlanticom I have created an autostop mod using and arduino nano and a few other things.

Here is a video of it in action.

Here is a diagram of my wiring.

I power the arduino using the usb port and a 5v phone charging wall plug.


Here is the arduino code.


//japanese pachislot autostop mod:
//mcrowell75 and Atlanticom 2021:
//This code was written for an arduino nano and a 4 channel relay module:
//It has been tested on an IGT "Popper King" pachislo:




int button_1 = 2;
int button_2 = 3;
int button_3 = 4;
int spin_in = 5;
int spin_out = 6;




void setup() {
pinMode (spin_in, INPUT);
pinMode (button_1, INPUT);
pinMode (button_2, INPUT);
pinMode (button_3, INPUT);
pinMode (spin_out, OUTPUT);


digitalWrite (spin_out, HIGH);
digitalWrite (spin_in, HIGH);


}


void loop() {
if (digitalRead (spin_in) == LOW) {

digitalWrite (spin_out, LOW);
digitalWrite (spin_out, HIGH);
delay (random (1000,3000));
pinMode (button_1, OUTPUT);
delay (100);
pinMode (button_1, INPUT);

delay (random (500,1500));
pinMode (button_2, OUTPUT);
delay (100);
pinMode (button_2, INPUT);


delay (random (500,1500));
pinMode (button_3, OUTPUT);
delay (100);
pinMode (button_3, INPUT);


}


}


There you have it. Thanks to atlanticom and everyone on the forum who helped me troubleshoot this machine over the last year.
