POW-Rduino testing tool

Step 15: Arduino Sketch

SKETCH FOR WORK THE TESTING TOOL:

This Sketch is just to get you started and will allow you to control the outlets in a very general way.  You can visit:

Luke Liseman and his "Garduino" design
http://www.instructables.com/id/Garduino_Gardening_Arduino/

Here you will find other sensors that you can play with.  These will safely work on the
POW-Rduino.

POW_Rduino SKETCH:

// Turn on LED when the button is pressed
// send sensor output to RELAY1 and RELAY2
// will be used to turn on high voltage outlets for POW-Rduino
// and keep it on after it is released

#define LED 13    // the pin for the LED
#define BUTTON 2  // the input pin where the pushbutton is connected
#define RELAY1 7  // pin for RELAY1 connection
#define RELAY2 8  // pin for RELAY2 connection
int val = 0;      // val will be used to store the state
                  // of the input pin
int old_val = 0;  // this variable stores the previous
                  // value of "val"
int state = 0;    // 0=LED off while 1=LED on

void setup() {
  pinMode(LED, OUTPUT);    // tell Arduino LED is an output
  pinMode(BUTTON, INPUT);  // and BUTTON is an input
  pinMode(RELAY1, OUTPUT);  // tell Arduino RELAY1 is an output
  pinMode(RELAY2, OUTPUT);  // tell Ardrion RELAy2 is an output
}

void loop() {
  val = digitalRead(BUTTON);  // read input value and store it                          
                        
                             
  // check if there was a transition
  if ((val == HIGH) && (old_val == LOW)){
    state = 1 - state;
  }
 
  old_val = val;    // val is now old, let's store it
 
 
  if (state == 1) {
    digitalWrite(LED, HIGH);    // turn LED on
  } else {
    digitalWrite(LED, LOW);     // turn LED off
  }

  if (state == 1) {
    digitalWrite(RELAY1, HIGH);  // singnal sent to RELAY1
  } else {
    digitalWrite(RELAY1, LOW);
  }
 
 if (state == 1) {
  digitalWrite(RELAY2, HIGH);  // singnal sent to RELAY2
 } else {
  digitalWrite(RELAY2, LOW);
 }
