Stap 3: Programmering/Code
Download het bestand aan het einde van de instructable of kopieer de volgende code in jouw Arduino-Intel IDE (Integrated Development Environment). Upload de code naar de Edison-bestuur. Rekening mee dat er verschillende aanpasbare parameters verschijnen in de code, het belangrijkst is een tekenreeks met de naam beat met letters die de sensoren worden geactiveerd op de beat en een unitsPerBeat die vertelt hoeveel tekens in een enkele beat gaan vertegenwoordigen.
