1. Load Cell (Weight Sensor): This is used to measure the weight of the feeding bag.
2. Load Cell Amplifier (e.g., HX711): This amplifies the small electrical signals from the load cell.
3. Microcontroller (e.g., Arduino, ESP32): Processes the data from the amplifier and calculates the remaining value and flow rate.
4. Display/Interface: To show the remaining value and/or flow rate to the user (e.g., LCD, LED display).
5. Power Source: To power the system components.
6. Supporting Components: Resistors, capacitors, wires, etc., as needed for building the circuit.

1. Connect the Load Cell:
   • Attach the load cell to the feeding bag. Make sure it is calibrated to measure the weight correctly.
   • Wire the load cell to the load cell amplifier (e.g., HX711).
2. Connect the HX711 to a Microcontroller:
   • Connect HX711:DT (Data) to a digital input pin on the microcontroller.
   • Connect HX711:CLK (Clock) to another digital input pin.
   • Connect HX711:VCC to the 3.3V or 5V output of the microcontroller (based on compatibility).
   • Connect HX711:GND to the Ground pin of the microcontroller.
3. Program the Microcontroller:
   • Write code to read data from the HX711.
   • Use this data to calculate the remaining weight.
   • Determine the flow rate by measuring weight change over time.
   • Use a library like HX711 for Arduino or ESP32 to simplify this task.
4. Display the Information:
   • Connect your display module to the microcontroller.
   • Display the remaining weight and flow rate values.
5. Assemble and Test:
   • Ensure all physical connections are secure.
   • Calibrate the load cell for accurate tracking.
   • Test the system by incrementally adjusting the weight and observing the output.

• You want a continuous readout of remaining weight and flow rate.
• The feeding bag is suitable for load cell attachment.
• Power consumption is manageable given your available resources.
