Controlling electronics with the Commodore 64 user port - Part 1

This is the first part of a series where I explore the possibility to use the user port on an old Commodore 64 8-bit computer from the 80-s, to communicate with other electronic devices, self made or for example an Arduino device.

In this part I construct the cable and connector I need, then I power a simple LED circuit from the Commodore.
