| 71 | +## Functional Overview |
| 72 | +The Modulino® Joystick reads the FJN10K-S1B10KD0N analogue joystick's dual potentiometers (horizontal and vertical axes) and the integrated pushbutton state. The STM32C011F4 microcontroller processes these analogue signals and provides digital values via I2C. The joystick offers 60° movement range in both directions with smooth analogue control and reliable centre positioning. |

| 142 | +#### Pull-up Resistors |
| 143 | + |
| 144 | +This module has pads for optional I2C pull-up mounting in both data lines. No resistors are mounted by default but in case the resistors are needed 4.7 K resistors in an SMD 0402 format are recommended. |
| 145 | + |
| 146 | +These are positioned near the Qwiic connector on the power LED side. |
| 147 | + |
| 148 | + |
| 149 | +## Device Operation |
| 150 | +By default, the board is an I2C target device. It continuously monitors the joystick's horizontal and vertical potentiometers plus the pushbutton state, providing digital values via I2C registers. The joystick returns to centre position when released, with values ranging from 0-4095 for each axis. Simply connect it to a 3.3 V Qwiic interface and read the axis positions and button state via I2C. |
| 151 | + |
| 152 | +### Getting Started |
| 153 | +Use any standard Arduino workflow-desktop IDE or Arduino Cloud Editor. The official Modulino library provides simple functions to read joystick X/Y coordinates and button state. The joystick values are automatically centred and scaled for easy use in gaming or control applications. |
| 154 | + |
| 155 | +### Joystick Output Values |
| 156 | +- **Horizontal Axis (X):** 0-4095 (left to right), centre ≈ 2048 |
| 157 | +- **Vertical Axis (Y):** 0-4095 (down to up), centre ≈ 2048 |
| 158 | +- **Pushbutton:** Boolean state (pressed/released) |
| 159 | +- **Centre Position:** Joystick returns to centre when released |
