Story

Steps for creating this motion-activated SMS sender:

Step 1

Connect your 1Sheeld to your Arduino
Connect the Arduino to your PC
Make sure the 1Sheeld's UART switch is open – otherwise the Compiler will give an error.
Upload this code to the Arduino:

http://codepad.org/tpikIYYI>http://codeshare.io/9Owvu

Edit the number “ 0123456789” to your Number SMS yourself or preffered phone

Step 2 (The LED)

Connect the led to pin number 13 and, with the resistor, to ground.

Step 3 (The PIR Motion sensor)

When you point the PIR motion sensor bubble away from you, to see the back with the 3 connector pins at the bottom, connect it like the following:

1. The left pin needs to connect to pin number 2,

2. The middle pin needs to be connected to 3.3V,

3. The right pin needs to be connected to ground on your Arduino.

PIR-motion sensor is connected right

Step 4 (Connecting)

Pair your Android device to your 1sheeld, via the 1Sheeld app, through Bluetooth
Select the following shields:

SMS shield, to be notified when something happens/ or motion is detected

Make sure that your number is typed in correctly and that the delay is more than 150ms

Step 5 (Ready to go)

Make sure the code is uploaded, and wait for the LED to switch off.
Switch the UART switch to closed, to begin communication between the 1sheeld and your phone.
Move infront of the motion sensor and wait for the SMS/

NOTE : MAKE SURE THAT YOUR NUMBER IS TYPED IN CORRECTLY, THE DELAY IS MORE THAN 100ms.

#include <OneSheeld.h> 
int ledPin = 13;                // choose the pin for the LED
int inputPin = 2;               // choose the input pin (for PIR sensor)
int PIR = LOW;    //Sets the Motion sensor to low        
int val = 0;

   OneSheeld.begin(); 

 
}

void loop(){
  //loop starts
  
    val = digitalRead(inputPin);  // read input value
  if (val == HIGH) {            // check if the input is HIGH
    digitalWrite(ledPin, HIGH);  // turn LED ON   
    delay(150);//delays the wait for 1/15 of a second 

    
    if (PIR == LOW) { //if motion is detected
      
       SMS.send("0123456789","Motion DETECTED"); 
       //^^^^^^^^^replace 0123456789 with your number, add your own Message
       PIR = HIGH; //sets the value to high so that we avoid a infinite loop
    
    }
  } else {
      digitalWrite(ledPin, LOW); // turn LED OFF

        
      if (PIR== HIGH){ // if its HIGH set to low sothat it is checked again


      PIR = LOW;
    }
    //loop ends an restarts
  }
