Hello Arduino community.
For the Fourth of July this year, I thought I would program my arduino uno to ignite fireworks for me with music playing. I have a basic plan, but as this is my first project, I would love guidance!
Each firework will have its own igniter made from steel wool. Wires will run back to the arduino and a battery in a fireproof box. All of the igniters will be connected to relays which are then triggered through shift registers connected to the arduino.
Can anyone foresee problems with this? I am beginning to work on building igniters and testing the ignition system, I will come back for more guidance if I run into any problems.
