The entire build is featured in this YouTube video. The project mostly worked as planned. There where 8 outputs that did not work (firework didn't go off). 4 of these were during a fast 100ms sequence which would have been awesome if they did work. Not sure where the fault was but assuming it was on my side. There could have been a wire disconnect but seems unlikely, the guy that connected them is pretty good.
Please enjoy the project build and let me know if you have any comments or suggestions, always looking for ways to improve.
novice question but what if you had enclosed the LED with the photoresistor to prevent the fireworks from triggering each other? or would that potentially overheat?
