This project is an accumulation of several smaller, simpler projects that I work on in the past. It all started out with LED’s in one project, a camp fire which turned to a welding scene, and IR sensor, and the use of a DF Player Mini for sound fx.
I had a narrow spot that needed some life that was right behind me whenever I recorded and did live streams. I started with just the welder with sound, but later saw a video by Dave Bodnar on lightning. This got me to thinking that I could incorporate the lightning sketch which operated off of a sound clip and use it for my welder scene.
I ended up using 2 Pro Mini’s for the project to hold separate sketches, since there was no way to combine all the different sequences together without interfering with the LED’s for the welder. It took many hours of trial and error, mostly errors, to get to a final working project.
The first Arduino holds the starting sequence of the IR Sensor, and sound from the DF Player, then triggers the second Arduino which has all the lights. Once the sketch runs for a specified amount of time, there is a shut down sequence on the second Arduino, then it passes control back to the first device which has it’s own shut down sequence.
