This project uses a simple RF link and two Arduinos to ignite something from up to 90 feet away! I always found it annoying to mess with a bunch of wire, so I felt like creating something to fix that problem. A wireless connection is not only safer, but also A LOT cooler. This wireless ignitor can be used to ignite fireworks, model rockets, and more!
This is PART ONE of a three part project! See the other parts by visiting my page!
Disclaimer: This is not intended to be used as anything but a safe way to ignite fireworks, a model rocket, etc. Be cautious whenever you are building this or using this device. I take no responsibility for any harm done due to any carless action or a failure to follow the proper safety measures.

Step 2: Getting VirtualWire
1.) This library can be downloaded directly from here, or on the website here.
2.) Find the location of your Arduino sketchbook by checking your Arduino preferences.
3.) Make a folder called "libraries" if it's not already there and place the VirtualWire folder in it.
4.) Open arduino and you're done!
