(ex. Did you make this project? It's simple to make and so easy to program. Thank you for following me through this tutorial, I hope thatsome of you will like it, and maybe even try it one day - it is really a soothing DIY : ), try to improve this launcher with your ideas. If you have questions or thoughts about this project, please do let me know, I would love to hear your feedback!See you at my next instructable! HC-06, password 1234)You can use the code witch attach with this pageNow you can feel free to control it your selfin this program i just use #1 for heat up the first heating coil & #2 for cut off the power #3 for heat up the other heating coil & #4 for cut off the power ( you can change the values in your own by changing the code )Note- Please dont power up the heating coil more than 5 seconds it may damage your battery, After making the circuit make sure all the thing attached well in order, Set this launcher in outdoor place and enjoy...( you can add it to your wall, vertical pipe or any thing else ). Retro Analog Audio VU Meter From Scratch! Share it with us! Firework Rocket Launcher It's simple to make and so easy to program. Providing customers a directional firing tube while helping keep customers hands and eyes safe. Nowadays so many people, specially children just enjoy with the fire works carelessly, so, I decided to create safety rocket launcher to minimize those damages instead of suggesting them, Here I am showing how to make a cheap Arduino bluetooth. mata podi prashnayak thiyenawa.dan hothamu api uda noyana ahas kurak thibba kiyala .eka uda noya oya dot doard ekedima pipiruwoth arduino eka damage wenawane. A unique design make it different from that of other Arduino bluetooth launchers. Participated in the Microcontroller Contest 2017. OPA Based Alice Microphones: a Cardioid and a Figure 8, 9V Battery / 2pcs of 3.7V 18650 Batteries( to power up the Arduino Board & attachments). Hope you like this idea and after this instructable, you can upgrade and change the features or anything else! A unique design make it different from that of other Arduino bluetooth launchers. Reply eka nisa okama atmega 328 dala hadana hati kiyannakooo. The Safety Rocket Launcher Firing Tube brings the excitement of shooting stick-attached rockets and the safety of a secure shooting mechanism together. Hope you like this idea and after this instructable, you can upgrade and change the features or anything else! 3 years ago. Mehemai eka aulk thama habai mama okedi use kale duplicate chinese clone ekk Arduino pro mini board eka dammth wensk naha oya widiyama thamai, About: Hello, I'm Tharinda Uthpala , From Srilanka. First you need to make the circuit as shown in the diagram.R' - 5v relaysD' - 1N4004 diodesD1 - Red LEDsR0 - 100ohm resistorsH' - Heating Coilwhen you making this circuit you can mix your own ideas with this For example: you can use 2pcs of 18650 batteries instead of 9v battery and also you can use Arduino pro mini board ( its just need very little space )Wiring Instructions -Bluetooth module - "TX of Bluetooth Module" goes to "RX of Arduino" - "RX of Bluetooth Module" goes to "TX of Arduino" - "VCC of Bluetooth Module" goes to "5v of Arduino"- "GND of Bluetooth Module" goes to "GND of Arduino" - The State & Key pins of the BT modules are unused.After making the circuit please make sure all the components well in order, You just need to buy a Nichrome coil from your local electronic shop or easily get it from old burn out soldering iron then place some copper rods like that to attach those coils, after that take a little rounded rod and make 3 or 4 turns by using it, Finally attach those coil into that copper rods very tightly, After making the coil you need to solder wires as shown in the picture , then solder those wires to relay coils, next you need to add 1N4004 diodes to relays ,finally add some jumper cables to them, After making the coil & relay circuit you need to attach Blutooth module and other things with Arduino board as shown in the pictures, You can use the below link to download the free applicationClick here to download the Android ApllicationThen Power up the circuitAfter that enable Bluetooth and establish connection with BT module. It is the only product on the market today that has a patented safety feature ideal for shooting bottle rockets, whistlers, skyrockets and large stick-attached rockets.
