Arduino Rube Goldberg Machine

Wikipedia says:

A Rube Goldberg machine, contraption, invention, device, or apparatus is a deliberately over-engineered or overdone machine that performs a very simple task in a very complex fashion, usually including a chain reaction. The expression is named after Americancartoonist and inventor Rube Goldberg (1883–1970).

Your task (DFI Masters students) is to create a Rube Goldberg machine out of a chain of Arduinos. Activated by a single human input, the output of one Arduino will be connected to the input of the next in a continuous chain until the grand finale is reached. You are each individually responsible for a node in the system but you must all work together in order to make the machine work as a whole. Fun! Here are your guidelines:

• Human input should be used at the first node and nowhere else.
• Simple and working is better than complex and not.
• Help each other. If your node is finished, move on to the next. You’re not done until the machine is done.
• If you need help, ask for it! The machine doesn’t work unless every part works.
• Check off your connection once it’s been made.
• Test early and often.
