This project is a modified version of the awesome instructable by deba168. You can view the original here.
I teach an 8th grade tech course, so the training will talk about kits we have in our room... Your tools may vary. I have the lesson cut into very short steps, but that is what I have found works best with my students. The class is essentially self taught as the students work through the modules they have chosen. I have more than 30 areas from them to study, during the 18 weeks they are with me.

Step 1: Obtain the Toys.
To complete this project you will need 2 arduino boards. I used a nano and a duemilanove for mine. You also need the following
- a pir motion sensor
- a buzzer
- resistor (I use 220 Ohm, but you may use whatever makes your day)
- 2 breadboards
- a wireless transmitting and receiving kit. I obtained mine from miniinthebox as shows in the the picture for less than 2 dollars.
- 2 arduino boards ( I have a duemilanove and a nano)
Step 2: Attach the Main Components
Attach the main parts as shown in the video
Step 3: Power Wires
Add wires for GND and Power
Step 4: Motion Sensor
Attach and wire-up the motion sensor.
Step 5: Load the Code for the Nano - Transmitter
You will need to have the virtual wire library available for this project. You can download it here.
If you have not added a library to your Arduino IDE before, this link will take you to a tutorial. It opens in another window, so this will be waiting for you when you return.
My Video shows the transmit code being loaded, since I have already put it on the student PC's... You will have to copy and past it into the Arduino IDE on your own.
Step 6: Moving on to the Reciever
Use the steps in the movie to add hardware to your breadboard.
Step 7: Add the Wires
Wire it up as the movie shows.
Step 8: Add the Buzzer
Integrate the buzzer as shown here. I like to note the signal wire for my buzzer because it is nice to be able to instantly unplug it when you get tired of the alarm sound. =)
Step 9: Upload the Code
Once again you must have the virtual wire library installed. It was explained in step 6 above.
My movie also talks about loading the receive code, but you will need to copy and paste it into your IDE.
Step 10: Uh... Good Luck Asking. =)
You can see here that I use phone charging plugs to power our arduino's once they have been programmed. You could also use 9-volt batteries or any other slick system to juice up your creation.
