Hello,
I've spent many months reading this great forum and i'm ready to build my first project.
I'm using VeraLite as controller with a serial gateway (USB) and i would like to build a window/motion sensor battery operated (2AA).

For the sensors I collected all the stuff:

• list itemArduino Pro mini

• list item2AA battery holder

• list itemDC-DC Step up regulator

• list itemRadio NRF24L01+ (directly linked to the step-up for power)

• list itemMotion HC SR501 (to PIN2 not used by radio)

• list itemReed switch

I hacked the Nano by broking the LED (since i wasn't able to desolder it)

Now i have some problem with the sketch, since i tried to fuse 2 different sketches (door/window and motion)

Can someone help me?

#include <MySensor.h>
#include <SPI.h>

unsigned long SLEEP_TIME = 120000; // Sleep time between reports (in milliseconds)
#define SKETCH_NAME "Binary / Motion Sensor"
#define SKETCH_MAJOR_VER "2"
#define SKETCH_MINOR_VER "0"

#define PRIMARY_CHILD_ID 4

#define PRIMARY_BUTTON_PIN 2   // Arduino Digital I/O pin for button/reed switch
#define DIGITAL_INPUT_SENSOR 3   // The digital input you attached your motion sensor.  (Only 2 and 3 generates interrupt!)
#define INTERRUPT DIGITAL_INPUT_SENSOR-2 // Usually the interrupt = pin -2 (on uno/nano anyway)

 
// initialize motion sensor
MySensor gw;
// Initialize motion message
MyMessage msg(CHILD_ID, V_TRIPPED);

//initialize window sensor
MySensor sensor_node;
// Change to V_LIGHT if you use S_LIGHT in presentation below
MyMessage msg(PRIMARY_CHILD_ID, V_TRIPPED);


void setup()  
{  
  sensor_node.begin();

  // Setup the Window
  pinMode(PRIMARY_BUTTON_PIN, INPUT);

  // Activate internal pull-ups
  digitalWrite(PRIMARY_BUTTON_PIN, HIGH);
  
  // Send the sketch version information to the gateway and Controller
  sensor_node.sendSketchInfo(SKETCH_NAME, SKETCH_MAJOR_VER "." SKETCH_MINOR_VER);

  // Register binary input sensor to sensor_node (they will be created as child devices)
  // You can use S_DOOR, S_MOTION or S_LIGHT here depending on your usage. 
  // If S_LIGHT is used, remember to update variable type you send in. See "msg" above.
  sensor_node.present(PRIMARY_CHILD_ID, S_DOOR);  
  }

{  
  gw.begin();
  
  pinMode(DIGITAL_INPUT_SENSOR, INPUT);      // sets the motion sensor digital pin as input
  // Register all sensors to gw (they will be created as child devices)
  gw.present(CHILD_ID, S_MOTION);
  
}
// Loop will iterate on changes on the BUTTON_PINs
void loop() 
{
  uint8_t value;
  static uint8_t sentValue=2;
  
  // Short delay to allow buttons to properly settle
  sensor_node.sleep(5);
  
  value = digitalRead(PRIMARY_BUTTON_PIN);
  
  if (value != sentValue) {
     // Value has changed from last transmission, send the updated value
     sensor_node.send(msg.set(value==HIGH ? 1 : 0));
     sentValue = value;
  }
// Read digital motion value
  boolean tripped = digitalRead(DIGITAL_INPUT_SENSOR) == HIGH; 
        
  Serial.println(tripped);
  gw.send(msg.set(tripped?"1":"0"));  // Send tripped value to gw 
  
  // Sleep until something happens with the window sensor
  sensor_node.sleep(PRIMARY_BUTTON_PIN-2, CHANGE, 0);

  // Sleep until motion interrupt comes in on motion sensor. Send update every two minute. 
  gw.sleep(INTERRUPT,CHANGE, SLEEP_TIME);
