Description Unit Joystick v1.1 is a joystick control input unit that adopts the I2C communication interface. It supports three-axis control signal input, including X/Y axis offset analog inputs and a Z-axis button digital input. The unit is suitable for joystick-control applications such as game controllers and robot remote control. The X/Y axis outputs provide analog values from 0 to 255, while the Z-axis button outputs 0 or 1. According to the official documentation, the unit uses I2C address 0x52 and returns 3 bytes when reading joystick status. Video Features Three-axis input: supports X/Y axis offset analog inputs and Z-axis button digital input. X/Y axis control: outputs values from 0 to 255 for joystick movement. Z-axis button: outputs 0 or 1 for button status. I2C communication: uses I2C communication at address 0x52. LEGO-compatible mounting: includes 2 LEGO-compatible holes. Development platform support: supports Arduino and UIFlow, including Blockly and Python.
