A hardware thesis was contributed for a wiring design by Colombian student Hernando Barragan. After the Wiring[7] platform was complete, researchers worked to make it lighter, less expensive, and available to the open source community. The school eventually closed, but the researchers, including David Cuartielles, promoted the idea. The Arduino core team consisted of Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino and David Mellis.[5]
