Story

Every day we used to see our mechanical garage people struggling so much to open the garage door which has a motor and control of the motor is through the switch. They wanted only authentic users to open and close the garage door and this has motivated us to design a smart phone controlled garage door control system.

Live demonstration of the project using MSP430G2553 LaunchPad.

Code for Motor Control via bluetooth

unsigned char temp;
int up=6;
int down=7;
int n=20000; // time of 20 sec for shutter up and down
void setup() {
  // put your setup code here, to run once:
Serial.begin(9600);
pinMode(up,OUTPUT);
pinMode(down,OUTPUT);
digitalWrite(up,LOW);
digitalWrite(down,LOW);
}

void loop() {
  // put your main code here, to run repeatedly:

   while(!Serial.available());
   if(Serial.available()>0)
   {
    temp=Serial.read();
    if(temp=='A')
    {
      digitalWrite(up,HIGH);
      delay(n);
      digitalWrite(up,LOW);
    }
    if(temp=='B')
    {
      digitalWrite(down,HIGH);
      delay(n);
      digitalWrite(down,LOW);
    }
   }
