Finished photo first. This is an arduino run LED strip that I can program to send messages to our party guests, or show various lighting effects.
First test to see how the glow functions worked.
Setting up the letters to figure out which LEDs light up which letters
Downloaded Something Strange for my letters (www.dafont.com/something-strange.font). Printed around size 500, but probably could have gone bigger.
This is the main loop of my program. I used the FastLED library for the LED control, and a switch/case and random number generator to have the program randomly select which subroutine to run.
Two of my subroutines have the LEDs go from off to red and back to off. I had to keep them in separate for loops because when I wrote them into one loop my program kept getting trapped.
This routine turns the LEDs on that light up the letters RUN, and then does some flickering on and off for added effect.
This is one of my tests (sped up) having it spell out I'm Here. The lighting is much better in the dark, but harder to record.
