I gonna make two ways for launch fireworks,
Way 1: Arduino and Exact Time
In this case I gonna use an Arduino Nano and RTC & LCD connected by I2C
Way 2: Using Photon
I simply will use the sample tinker app for activate an Output PIN
Now I have to integrate the arduino code on Photon.
It is the first time I do this for that libraries.
Finally I need an activator, which generates a spark and ignite the wick.
I was trying with a small cigarette lighter but I think I need a lighter with batteries, as soon I got this i will update the recipe. ;)
