CNC Plotter/Engraver – Atari Joystick Control Port Schematic

faq_controller_pinout

Our project revolved around the input from a user. In order to transfer user input to our plotter we needed a familiar physical object that could tell our device how to move on an X and Y axis grid. In this case we chose a joystick from an Atari game system. We then found this input schematic and soldered an adapter from the joystick to our breadboard where we then tested it out using LED’s. This joystick would then be hardwired into our A3BU to tell it when to send a voltage to the different motors.
