Blink Sequencing
In Add a Light you built a second LED and wrote scripts to control both of them. In Intro to Lists, you got to see how to create and access lists. In this activity, you will add a third LED, and then use lists to set up custom LED on/off sequences. You will even use a list of LED pins and a list of on times in the same for loop to fully customize the light sequence.
