Just recycling a broken nunchuk (connectors squashed, hence the hot glue) and testing the WiiChuck library over the Rotatey Cube before calibration.

The nunchuck shares I2C bus with the OLED where x/y/z acceleration data is fed to the cube.

Next step is testing the joystick with some Arduino games.

Hardware used:

• Wemos Mini D1
• OLED SSD1306 (I2C)
• Wii Nunchuk
