Squirreliminator® Humane Electric Fence Driver

3//This device is a controller trigger to generate a safe and humane pulse to operate a electric fence energizing coil. It operates economically
4//The very low duty cycle ensures long battery life and low power drain. The simple code is foolproof and there are ample opportunities for expansion

7// the setup function runs automatically upon powering up the Device. No switches or other inputs are required

15// the loop function runs over and over again forever
16void loop() {
17  digitalWrite(LED_BUILTIN, HIGH);   // Turns on the onboard LED for a brief flash, synchronous with the coil pluse - indicates function
18  delay(80);                       // 80 MS pulse generates a quick LED flash that is still easily visible
19  digitalWrite(LED_BUILTIN, LOW);    // This turns off the internal LED
20  delay(1200);                       // This makes a 1.2 second LED off cycle, corresponding to the 1.2 second coil-rest time
21  digitalWrite(8, HIGH);             // This turns pin 8 "high" or on, which outputs a 5VDC trigger pulse to the coil power module
22  delay(25);                         // This determines the duty cycle of the coil. 25ms is plenty long enough to get the coil fire
23  digitalWrite(8, LOW);              // This turns OFF pin 8 and deengergizes the coil
24  delay(1200);                        //This delay is the 1.2 seconds between coil impulses. The bigger this number, the less frequent the pulses
