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 two part project I am designing, so stay tuned for the rest!! (following me is a good way to do that) (Hint: It involves a cannon...)
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.
