I have a code of an interrupt sequence for a 3-way traffic light but I can't seem to get it to actually interrupt, can anyone help me?

int r1 = 1;
int y1 = 2;
int g1 = 3;
int r2 = 4;
int y2 = 5;
int g2 = 6;
int r3 = 7;
int y3 = 8;
int g3 = 9;
int button = 12;
int pedred = 10;
int pedgreen = 11;
unsigned long cTime = 0;
unsigned long wait = 0;

void setup() {
  pinMode (r1, OUTPUT);
  pinMode (y1, OUTPUT);
  pinMode (g1, OUTPUT);

  pinMode (r2, OUTPUT);
  pinMode (y2, OUTPUT);
  pinMode (g2, OUTPUT);

  pinMode (r3, OUTPUT);
  pinMode (y3, OUTPUT);
  pinMode (g3, OUTPUT);

  pinMode (pedred, OUTPUT);
  pinMode (pedgreen, OUTPUT);

  pinMode (button, INPUT);


  attachInterrupt(5000, changeLight, RISING);

}

attachInterrupt(5000, changeLight, RISING);

What pin is interrupt 5000 associated with?

What generates the interrupt? Which Arduino, different ones have different interrupts?

Are you trying to use attachInterrupt() for your button so you can avoid learning how to write non-blocking code? There are valid uses for attachInterrupt(), but that's not one of them.

I'll repeat what I wrote in your other thread:

pert:
Because of your use of delay(), your code only reads the button once every 16.5 seconds. This might make it seem that the button is not working. This is why you should never use long delays in your code. Instead, use millis(), as demonstrated in File > Examples > 02.Digital > BlinkWithoutDelay and this tutorial:
https://www.arduino.cc/en/Tutorial/BlinkWithoutDelay
