Playing Spin Rhythm XD with a Modified DJ Hero Controller

A few weeks ago, a friend of mine introduced me to a new rhythm game. Unlike previous titles such as Guitar Hero or Rock Band that use multiple discrete buttons in order to match different notes, this game used a virtual wheel – an analog input to slide, spin, and tap along with the beat. To top it off the game featured an electronic music tracklist and was a blast to play.

The game is called Spin Rhythm XD, and it was designed to be played with a DJ MIDI controller. Having no such professional DJ-ing equipment handy I decided to do the next best thing: convert my old plastic Wii DJ Hero turntable into a controller for Spin Rhythm XD!

Experiment: Wii Nunchuk Controller for CS:GO

Earlier this week I was browsing Reddit and came across this interesting post of someone playing a game of Counter-Strike: Global Offensive (CS:GO) using a Wii Nunchuk to aim. They used a cheap Chinese “Classic Controller to USB” adapter to connect the Nunchuk to their PC, then set up JoyToKey to convert the gamepad inputs into mouse movements.

This was pretty interesting, but I thought I could do one better. You see, I’m currently working on my own project that uses two Nunchuks for a custom controller. So when I ran across that Reddit post, I already had a breadboard on my desk with a Teensy LC, two NXC breakout boards, and two Wii Nunchuks wired and ready to go. Destiny was calling…

How to Use a Wii Nunchuk with an Arduino

When the Nintendo Wii was released in 2006, there was a lot of talk about their new weird control system. In place of a typical control pad, players would use a one-handed “remote” with infrared sensors and accelerometers in place of a joystick. For those games that required additional controls, players would use an accessory controller in their off-hand.

This ‘accessory’ controller is the Nunchuk. A strange, bean-shaped attachment with a joystick, two buttons, and a three-axis accelerometer. Although the Nunchuk had a lukewarm response when it was first released, it’s the perfect controller for makers who want to add some fine control to their projects.

Although I’m writing this post with Arduino in mind, most of this information also applies to using a Nunchuk with something like a Raspberry Pi or an ARM-based board.

Let’s get started!
