NOTE: This project involves the use of 120V AC line voltage outside and in possibly bad weather. THERE IS A DANGER OF ELECTROCUTION AND DEATH if you are not careful. If you are not comfortable with this, either do not attempt this or seek professional advice from an electrician or other adequately trained person. I expressly disavow any guarantees, promises, warranties, or claims regarding the safety of this project. You undertake it at your own risk.
If you've decided to continue on, great! This project can be adapted to something besides a dreidel; it could be any interactive light display you want.
The project consists of the following major steps:
1) Constructing the symbols from coat hanger wire and attaching rope lights.
2) Constructing the Arduino controller box along with wiring for the lights.
3) Programming the Arduino.
4) Putting it all together.
This Instructable includes the schematics (Eagle files) and code for this project. I assume that you have the ability/knowledge/comfort to do the following:
1) Etch your own circuit board and solder components.
2) Conduct basic wiring (connect an extension cord cable to a plug, strip wire, etc.)
3) Work with basic hand tools.
If you're new to working with circuit boards, there are numerous tutorials out there on Instructables and at places like YouTube.
Check out the video below to see it in action. (And, yes, I know, shin means put one in the pot, not lose everything.)
