Timer less Gate sensor system

Example code for an arduino.

The code uses the button de-bouncing library "Bounce" found here Link

Open the provided 'timer-less gate sensor example.config' in the configuration menu to load the correct gate codes.

#include <Bounce2.h>
#define LANE1_GATE1 2
#define LANE1_GATE2 3
#define LANE1_GATE3 4
#define LED_PIN 13
// Instantiate a Bounce object
Bounce debouncer1 = Bounce();
Bounce debouncer2 = Bounce();
Bounce debouncer3 = Bounce();
void setup() {
   // Setup the buttons
   pinMode(LANE1_GATE1,INPUT);
   pinMode(LANE1_GATE2,INPUT);
   pinMode(LANE1_GATE3,INPUT);
   // Activate internal pull-up
   digitalWrite(LANE1_GATE1,HIGH);
   digitalWrite(LANE1_GATE2,HIGH);
   digitalWrite(LANE1_GATE3,HIGH);
   
   // After setting up the button, setup debouncers
   debouncer1.attach(LANE1_GATE1);
   debouncer1.interval(5);
   debouncer2.attach(LANE1_GATE2);
   debouncer2.interval(5);
