Description

This is a basic firework launch controller based around an arduino nano/ micro. It can also be used to controll any dc appliance in a timed sequence, up to 24A/10A. The boards are designed with osome costumizability, as it is'nt a completeed project (there will more then likely be a v3.0) and has a lot of unused pins on ics and connectors. Basic functionality: maualy fire any channel open circuit failure test setting timer between each channel by pushing channel +/- to select channel (test fail/ok LED indicates selected channel) then pushing time+/- to set timer (10 to 390 sec,7segment LED displays indicating currently set time) Automatic fireing of all channels in timed sequence (timer set as above key switch to switch between safe(test) and live(applies 12 volts to dsub1_9) enter "programing mode" by pushing ch+, exit by pushing start internal or external start signal this build requiressome external parts not included in the scematic (for simplifying pcb design) such as: 10+5 momentary push buttons (no) 10 red 10 green LEDs key switch main power switch and connector some extra cable and headers
