Cabling / Programming 

  • The cabling might take time and have to be done properly to avoid destroying any component. Following all the instructions provided by the producer might help : this is pretty straight forward. The schematics are not yet available, I'll upload them soon.
  • For the source code, just play ! This is a simple three buttons machine ! You'll find all the component library easily on github.
