Hi there. :)

Are you still monitoring this Post? I am new to GitHub & signed up so I can speak w/ you about this code inspired to program lights for an Instructables "Stranger Things" display. 1st: Will I receive an alert once you reply to this Post? 2nd: If not I would greatly appreciate an email: SmartAlyx2@gmail.com 3rd: My sister & nephew are huge Stranger Things fans. I would really like to create the x-mas lights display for them. I really want to be able to program it to "write" specific messages. There are 26 letters in this alphabet. Add 0 - 9 numbers = 36 lights needed. Do you recall if Winona Rider painted punctuation marks? If not I would like to add @ least a period & question mark for a total of 38 lights needed. The special programible lights, do they come in the larger bulb size Winona used that have @ least 38 lights? Does your code spell out a message? If so, what? Is it possible to run the special lights off AC instead of DC?

Guess that is enough questions for now. My soon to be 12 year old nephew knows more about programming than I do because of MineCraft. After I get this set up I am going to hopefully know enough to show him how to program his own messages. :)
