DIY Arduino based Fireworks Firing System

by fsbutko on Tue Jun 15, 2021 11:51 am

Since it is getting close to the July 4th holiday, I'd like to continue what's become sort of a yearly tradition and share my DIY fireworks controller with everyone. The remote contains an Adafruit ItsyBitsy M0 on a custom circuit board along with an Adafruit NeoTrellis keypad and OLED character display. The Field module which connects to your fireworks basically has a standalone Arduino Uno that controls a multiplexed arrangement of solid-state relays which provide the battery current to the electric igniters which in turn shoot off the fireworks. The remote controller and field module talk to each other over a pair of RFM69HCW 915MHz radio modules.

Please let me know what you think and any comments or suggestions, I'm always improving upon this system year after year.
