Connect your Commodore 64 to the internet for under $10? Let's see how!
In Part 1 we blinked an LED using the Commodore 64 User Port, in Part 2 and Part 3 we got input from the user port and analog signals from the control ports. Now let's kick things up a notch and integrate our C64 with Arduino!
In Part 1 we blinked an LED using the Commodore 64 User Port, and in Part 2 we read binary (on or off) input also using the User Port. In this part we will use the Control Ports to read Joystick input and also analog signals.
