If you have one arduino board (Me!) and want to keep a project together, tape all the wires together in the correct order for a kind of plug.

An homemade 12V polarity tester.

Parts used:

  1. An old pen
  2. 2x LED diodes (red and green)
  3. some wires (22 and 16awg)
  4. 2mm thick steel thread
  5. some hot glue
  6. steel hook.


That's actually genius. :open_mouth:
