Programming LEDs with Arduino 201: A dynamic rainbow ASCII marquee
I’ve been teaching Arduino LED programming classes as VHS and now MakerLabs here in Vancouver. Together we learn how to write a simple Arduino program that introduces conditions, loops, variables, and methods. It seems to go over pretty well.
Yesterday made an LED light grid and programmed it with an Arduino with @marginallyc. My first Arduino project! pic.twitter.com/SRfw2PhDNA

At the end of the class I told people I would post a 201-level example of a dynamic scrolling ticker marquee. Word is bond, yo.
How to
– Upload this code same as in the class.
– Open the serial window.
– Set baud to 57600 and “send newline”.
– type a message at the top of the serial window and hit “send”. Your message appears on the marquee.
– Read through it to see how it be like it do.
