Arduino Project - Auto Scale

Project using Load Cell Sensor with Python UI for Graphs

Materials:

• Arduino Uno board
• Load Cell Sensor (any weight)
• Hx711 Amplifier
• Some wires
• Breadboard (optional)

Software:

• Arduino IDE
• Python
• VS Code (optional)

Usage:

1. Clone this repository: Arduino Project
2. Open the project in VS Code.
3. Navigate to /Arduino/main.ino and open main.ino.
4. Connect the Arduino board, Hx711, and Load cell sensor with the provided configuration.
5. Connect the Arduino board to the PC using a USB connector.
6. Identify the port of the Arduino.
7. Go to /Python/main.py and open main.py.
8. Modify line 30 in main.py to match the Arduino port.
9. Upload and run main.ino.
10. Run main.py.
11. Observe the graphs.

Configurations:

• In settings, adjust the accuracy for calibrating the graphs output.
• Click "calibrate". Ensure no materials are currently on top of the sensor, then click "start".
• Wait for the list to stabilize, then click "ok".
• Add the weight and input the known weight of the object in the popup using kilograms. Click "start".
• Wait for the list to stabilize, then click "ok".
• Verify if the measurements are correct by observing the graphs.
