Automatic Door Opener using IR Sensor and Arduino

Major Components

1 / 4 • L293D DC MOTOR DRIVER

Day by day all operations handled by man becoming an automated, in this regard one of the operations like opening of gate/door in unman condition, it is to be opened by automatically when person comes near to the door/Gate. This senses the presence of man/object near to it and gate is automatically opened and closed by itself. the time can be derived by user in program as delay. Here we are trying to do a small project on automatic Gate opener using arduino and IR Sensor. it will be a very cool and very interesting projec and can be used this for car garage as well as main gate.

Instructions

Connect the 5V ofthe Arduino to the positive of the IR sensor

Connect the ground to the ground of IR sensor and LM293D driver

Connect D0 and D1 of Arduino to IN2, IN1 of LM293D driver resectively

Connect dc motor terminals to pin3, pin6 of LM293D driver

Connect output of the IR sensor to the A0 pin of the Arduino

Check the connection once again

Download the ino sketch to Arduino UNO using Arduino IDE

Place the anyobject near to IR Sensor

Now your projectwill starts working

DOOR_DC

#define doorsensor A0
#define m1 0
#define m2 1

void setup() 
{
  pinMode(m1, OUTPUT);
  pinMode(m2, OUTPUT);
  pinMode(doorsensor, INPUT);
  delay(300);
  }

void loop() 
{
  if(digitalRead(doorsensor))
  {
    digitalWrite(m1, HIGH);         // gate opening
    digitalWrite(m2, LOW);
    delay(350);
    digitalWrite(m1, LOW);          // gate stop for a while
    digitalWrite(m2, LOW);
    delay(300);
    digitalWrite(m1, LOW);           // gate closing
    digitalWrite(m2, HIGH);
    delay(350);
    digitalWrite(m1, LOW);            // gate closed
    digitalWrite(m2, LOW);
    delay(1000);
  }
  
  else 
  {
    digitalWrite(m1, LOW);
    digitalWrite(m2, LOW);
  }
}
