How to Remotely Operate a Wii Controller B Button

Working on a project that requires a remote switch to create a circuit to work the B (Trigger) Button of a Nintendo Wii controller. I successfully soldered a phono cable inside of the controller. However this is a rather crude way of accomplishing this.

What I would like to do is have my single switch plug into the back of the Wii Controller. Using a nunchuck plug.

I came to this website because it lists a Wii Controller Driver board, and thought I might find help here. I am very new and could use any basic help in accomplishing my goal.

Thanks,

You have an awesome question! You can access all the Nunchuck signals (buttons, accelerations, joystick) trough the I2C interface. You simply need to plug the the Nunchuck to an Arduino with the Nunchuck adaptor.

Then you can translate the I2C communication to any pin or action you want to be done in the Arduino microcontroller. You can find here all the instructions and the required code to do this.

Also, if you meant the Wii Remote, You can communicate to it wireless via Bluetooth.

A quick Google search for “Wiimote bluetooth” SHould get you all the information you need.
