DIY Doggy Door using the Arduino Board

Here is my push button doggy door.  I have 1 Arduino UNO board, 1 relay board. AC to 24VDC power supply, 2 push button switches, motion sensor, IAI Electric Cylinder Actuator. The frame is made out of T80 and aluminum. It took some trial and error and some redesigning. But I finally got it. 








Below is the first proto type.   The threaded rod kept  seizing forcing me to re-think my idea.








 Code


void setup(){
  //start serial connection
  Serial.begin(9600);
 
  pinMode(7, INPUT_PULLUP); // Pushbutton
  pinMode(13, OUTPUT);   // doggydoor Open
  pinMode(12,OUTPUT); // Doggy Door shut
}
void loop(){
  //read the pushbutton value into a variable
  int sensorVal = digitalRead(7);
  //print out the value of the pushbutton
  Serial.println(sensorVal);
 
  // Keep in mind the pullup means the pushbutton's
  // logic is inverted. It goes HIGH when it's open,
  // and LOW when it's pressed. Turn on pin 13 when the
  // button's pressed, and off when it's not:
  if (sensorVal == HIGH) {
    digitalWrite(13, LOW);

  }
  else {
    digitalWrite(13, HIGH);
    delay(10000);
    digitalWrite(12,HIGH);
    delay(10000);
  }
}
