You can check the connections below there. I've also attached a fritzig schematic in png and fzz format. A smartphone capable of bluetooth connection ( i use an android in the example ) with a bluetooth software installedīasic arduino programming, this tutorial might be useful. Laptop with ArduinoIDE installed to program the arduinoĨ. USB to serial FTDI adapter FT232RL to programm the arduino pro miniĦ. Soldering iron for soldering wires to the LiPo connectorsĥ. Heat Shrink Tubing or insulating tapeĪssuming you don't have any of these parts the total will be 20$, but changes are that you'll have at least some of the components. XT-60 female LiPo connector ( eBay) 1.2$ġ0. I've chosen an battery with XT-60 connectorĩ. LiPo battery ( Hobbyking), or you can experiment with other batteries, i've chosen the LiPo because it's packs a lot of punch for it's size and we are not in danger of damaging it (it can handle relatively large currents). 3 AAA enclosed battery case ( eBay) 1$ you may use any power source that has between 4 and 11 V to be safe.ħ. You only need a few but i assume you have this alreadyĦ. male-male and male-female jumper wires ( eBay) 1.2$ x 2 for a bunch arduino pro mini 16Mhz 5V type ( eBay) 2$Īny arduino model will do, i've choose this one because it's small and cheap. Warning: The prices might vary a bit, those wore the prices available when i've created this instructableġ. Tip: enlarge the pictures to view the descriptive labels on them * Simple arduino bluetooth tutorial: here * fun, well there is only fun to create something with your hands, and you are free to adapt the project as you wish if it seems to simple (i'll give you some ideas at the end)īecause this is a beginners tutorial, i've selected links to some useful information below: * safety (you can operate it from a distance), the innocent firework there might not be dangerous but it can be adapted for more dangerous ones with only a match! * can be extended to multiple ignition only if necessary (i'll explain how) but for starters it's just a single igniter * a high level of details on this tutorial I estimate only an hour on work on the project * simplicity: the project will be made with little soldering on a breadboard and the components might then be reused easily. * low cost, the total parts with the battery included are under 20$ (you can see a list below) if you don't have any parts There are quite a few fireworks projects out there, why is this different. That didn't sound that complicated right ?įirst of all, i need to explain why i've made this project. The nichrome will heat quickly and become red and hot triggering the firework. 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 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. This is a project for beginners in which we'll be lighting fireworks using our bluetooth enabled phone.
