Simple and Cheap Phone Controlled Fireworks Igniter

STORY

What is this and how does it work?
This is a beginner project in which we'll be lighting fireworks using our bluetooth enabled phone.

The phone will trigger the firing event, the listening bluetooth module (HC-05) will communicate that to an arduino, and the arduino itself will trigger a relay. The relay will be connected to a LiPo battery and will drive current through a ribbon of nichrome wire wired around the firewok / match. The nichrome will heat quickly and become red and hot triggering the firework.

That didn't sound that complicated right ?

First of all, i need to explain why i've made this project. There are quite a few fireworks projects out there, why is this different. So i think it's advantages are:

* low cost, the total parts with the battery included are under 20$ (you can see a list below) if you don't have any parts

* simplicity: the project will be made with little soldering on a breadboard and the components might then be reused easily. I estimate only an hour on work on the project

* a high level of details on this tutorial

* can be extended to multiple ignition only if necessary (i'll explain how) but for starters it's just a single igniter

Other advantages but not so unique are:

* safety (you can operate it from a distance), the innocent firework there might not be dangerous but it can be adapted for more dangerous ones with only a match!


* fun, well there is only fun to create something with your hands, and you are free to adapt the project as you wish if it seems to simple (i'll give you some ideas at the end)


That being said let's get started!
