This project is about me messing around with the segmented display, and the joystick. then I made this.

EXPANDED TECHNICAL DETAILS

Dynamic Graphical Logic Interface

This project uses a 2-axis analog joystick to interactively control individual segments of a 7-segment display, providing a deep-dive into coordinate mapping and multiplexing.

  • Joystick Quadrant Mapping: The Arduino captures the X and Y analog values (0-1023). The firmware divides the joystick's range into 8 "Sectors" corresponding to the physical circular arrangement of the segments (A, B, C, D, E, F, G).
  • Proportional Segment Illumination: As the user moves the stick toward a quadrant, the Arduino illuminates the corresponding segment. The "Center" click of the joystick is mapped to the middle segment (G).

Accuracy

  • ADC Noise Debouncing: Includes a software "Dead-Zone" around the center position. This prevents the display from "Flickering" when the joystick is at rest, ensuring a stable and professional user experience.
