NES Controller

The article will guide you on how to use NES controller in Atari 2600 or ZX Spectrum using an Arduino. Read through the entire article to have a better idea. An arduino and a few connectors are the only components involved here. Since the source code is small, any Arduino board can be utilized. The detailed list of components involved is mentioned below:

    Arduino
    DB-9 Male connectors – 2 nos
    DB-9 Female connector
    5 Leds for the test dongle
    5 resistors 330 Ohms 1/4 Watt for the test dongle
    Connecting wires

The DB-9 female plus wires can be replaced by a used Atari Joystick cable if required. The NES cable also can be cut and connected to the arduino. But the wires should be identified without any confusion. The source code is compiled and uploaded to the Ardunio. IDE version 0.22 was used to develop the code. In order to observe the exact behavior of the circuit, a dongle has to be used before the circuit is conneced to the ATARI. Buttons on the NES controller are used to activate the LEDs in the dongle.

The Arduino board has to be powered if a dongle is used for testing the circuit. The joystick controller provides the necessary power that is required for the Arduino to function. No external power is required in this case. This marks the end of the design and testing. The controller is now complete and ready for use.
