Wouldn't it be nice to ignite more than one firework at the same time? Or even have a safe distance to more dangerous explosives. In this project I will show you how to build a circuit which can do just that with the help of the Bluetooth functionality of your smartphone. Let's get started !

Step 1: Watch the Video!

The video gives you an overview of what you need to do to build something similar. In the following steps I will present you more in depth information about it.

Step 2: Order Your Parts!

Here you can find all the parts that I used during this project:

Step 3: The Wiring!

Here you can find the schematic and pictures of how my final circuit and wiring inside my project box looks like.

Step 4: Program You ΜC!

Use the Arduino IDE and my sketch to program your ATmega.

Step 5: Download the App!

Here you can download the .apk file for your Android phone or the .aia file to import the project in your account of the MIT App Inventor.

MIT App Inventor: http://appinventor.mit.edu/explore/

Step 6: Success!

You did it. You just created your own Remote Bluetooth Igniter!

Sir can u please send a same complete project. I want to bye a same project kit.
Can you make classes of arduino and microcontroller programming
<p>I MADE MY OWN PROGRAM! </p><p>https://drive.google.com/open?id=0B_7DN-NFLZbyNUZCWXFBZnZfV2s</p>
<p>Will this work with a 12v Lead Acid Battery?</p>
Will this project work with the HC-05 bluetooth module ?
<p>I think so</p>
<p>Hi how can i unzip the .aia file because when i unzip it the usual way, then there is now .aia file in the folders. I'm using win 10 </p><p>Thanks already!</p>
<p>There's a way to dowloand the wiring diagram in high quality to make zoom ?</p>
<p>You can dowload the pictures</p>
<p>Yes but when I donwload it and I make zoom is in poor quality and I can't read the values.</p>
<p>You can dowload it in its original resolution. It is not that hard. </p>
<p>Hello GreatScott! Can I use an ATtiny85 instead of the ATmega 8-16PU? Thanks</p>
<p>It is way harder to do because you need to create a serial connection to the bluetooth module through software. </p>
<p>Ok I will try in the breadboard. Thanks! And congratulations for your videos!</p>
<p>Yes, but you have less programming space and io pins to use. But it should be possible.</p>
<p>Ok thanks Stephan2!</p>
<p>I would suggest getting a roll of nichrome wire (around 26 or 28 AWG) for the igniters. Wrap 3 turns tightly around the fuse and clip your leads on. It lights in less than a second and doesn't stink like a burning resistor.</p>
Model rocket ignitors are cheap.
<p>Nichrome igniters cost less than 1 cent each if you get a 100 foot roll from ebay.</p>
<p>Yes, but you will have to work with alligatorclips. And GreatScott is using a Li-Po battery, so nichrome has a potential to short the battery (resistor may als short), and in case of a Li-Po that is not a great idea. But Ni-Cd and mains adapter would be okay with that!</p>
<p>GreatScott!, As always beautifull tutorial!. I like your videos a lot!<br>I do have a question for you. Do you know if I can use a LM350T Voltage regulator instead? I have them hanging around. Thanks in advance!</p>
<p>Is there a reason to use the ATmega 8? Can I use another type of ATmega?</p>
<p>You can use other types as well. </p>
<p>That is awesome and clever idea .</p>
<p>Awesome, and I agree 100% with the lockout pin idea. After having a model rocket ignite while putting the alligator clips on the igniter wires, it teaches you a nasty little lesson about safety first! </p>
<p>I like this project a lot. I'm always a fan of being able to blow pyro up from a safe distance. But being a paranoid SOB who has seen Mister Murphy come along more than a few times to mess up my projects, and once or twice have things blow up in my face, I'd suggest adding a positive mechanical/electrical lock out of some kind. </p><p>Something that you can remove and put into your pocket that makes the thing safe from accidental ignition. A key switch perhaps, or a plug that you can remove that completely removes power from the thing. If this comes to the attention of whatever government agency they will insist that something like that be installed. </p><p>Don't depend on a software lockout, or bluetooth signal security. Some clever twelve year old will hack past your electronic protection and think it is the funniest thing in the world to set your pyro off just as you stand up and start to walk away after setting it up. </p>
This would be great for model rocketry, or even for a remote controlled fireplace (with addition of a valve control)
<p>now i can ignite my bombs safely, jk</p>
Rather than this I think you can use some paper matches wire arduino and bluetooth module for making a simple igniter! That would be way easier than this
