Step 7: Using It
Once it is finished, get the Estes rocket igniter tabs OR some nichrome wire, hook it up to the alligator clips, wrap it around the end of the fuse on the firework you want to light, Then back away. Next, all you have to do is point an ordinary TV remote (or any other kind of IR remote for that matter) at it, and push any button, and PRESTO! You've got a firework lit, and from a safe distance!
Notes: The 'signal LED' and the buzzer are simply indicators (and as a warning) that the signal from the remote has been received, and the firework is being lit. You don't HAVE to have these, but they are good to have as a safety precaution, and they make it look cooler.
Further expansion ideas: add multiple igniter leads for neat, timed fireworks displays with multiple fireworks; expand software to do so.
