This project implements a scoring system for French boxing (Savate) using an ESP32-C3 Mini microcontroller. The system allows referees or judges to increment points using three buttons, each representing a specific point value. A reset button is also included to reset the score. The current score is displayed in real-time on a TM1637 4-digit display.
- Scoring Buttons:
- Button 1: Adds 1 point to the score.
- Button 2: Adds 2 points to the score.
- Button 3: Adds 4 points to the score.
- Reset Button: Resets the score to zero.
- Real-Time Display: A TM1637 display shows the current score.
- Compact Design: Utilizes the ESP32-C3 Mini and built-in pull-up resistors for simplicity.
- Microcontroller: ESP32-C3 Mini
- Display: TM1637 4-digit 7-segment display
- Buttons: 4 push buttons (3 for scoring, 1 for reset)
- Power Supply: 3.3V for ESP32-C3 and TM1637 module
- Arduino IDE or PlatformIO
- USB-to-Serial interface for flashing the ESP32-C3 Mini
| Component | Pin/Connection | ESP32-C3 GPIO |
|---|---|---|
| TM1637 CLK | CLK | GPIO1 |
| TM1637 DIO | DIO | GPIO2 |
| Button 1 | One terminal | GPIO3 |
| Button 2 | One terminal | GPIO4 |
| Button 3 | One terminal | GPIO5 |
| Reset Button | One terminal | GPIO6 |
| Other Button Pins | Ground (GND) |
Note: The buttons are connected between the respective GPIO pins and GND. Internal pull-up resistors are enabled in the firmware.
The following library is required for this project:
- Clone this repository:
git clone https://github.com/your-username/boxing-score-counter.git cd boxing-score-counter
Open the .ino file in Arduino IDE or PlatformIO. Install the required library (TM1637Display). Flash the code to your ESP32-C3 Mini. Logic Overview The firmware reads the button states and increments the score based on the button pressed. The TM1637 display is updated in real-time. The reset button clears the score.
Buttons are configured with pull-up resistors. When a button is pressed, its state is LOW.
Points are added to the score based on the button pressed:
- Button 1 → +1 point
- Button 2 → +2 points
- Button 3 → +4 points
- The reset button sets the score back to zero.
- The TM1637 display shows the current score in real-time.
Incorporate a buzzer to signal scoring events. Add wireless capabilities (e.g., Bluetooth) for remote score tracking. Add a timer to track rounds or match duration.
