Programmable firework firing system with remote control
This project is using the Arduino Nano and WS2811 LEDs for a 50 channel (cues) remote firework firing system.
One of the best features of this system is that you can visually test the program's output before connecting it to any fireworks by watching the LEDs light up.
Total cost was $98.84 Parts List (search for any of these on Amazon and you will find it) $9.20 NPN BC337 $9.34 GL5528 Photoresistor $22.86 E-matches $7.49 22 AWG power wire $13.99 Wireless Control Switch $7.50 2 pin 5mm Screw Terminal $5.00 Arduino Nano $15.99 WS2811 Addressable LEDs
This project used "FastLEDS" library to control the WS2811 addressable LEDs.
