## Troubleshooting
### Common Issues and Solutions
- **No Communication Between Transmitter and Receiver:**
- Ensure the nRF24L01 modules are correctly connected to both the Arduino Nano (transmitter) and Arduino Mega (receiver).
- Verify the power supply to the nRF24L01 modules. If the modules are not receiving sufficient power, they may not function properly.
- Check the wiring of the SPI pins (MISO, MOSI, SCK, CE, CSN) for any loose connections or incorrect pin assignments.
- Ensure the correct addresses are used for communication in the code (both transmitter and receiver should match).
- **Water Level Data Not Displaying Correctly:**
- Check the ULN2003 IC connections to ensure the water level sensors are providing accurate input to the Arduino Nano.
- Verify the sensor calibration and check for any dirt or obstructions affecting the sensor's operation.
- **Touchscreen Not Responding:**
- Recalibrate the touchscreen using the `TouchScreen.h` library if the touch input is inaccurate or unresponsive.
- Ensure the touchscreen wiring is correct, especially the connections for the `X` and `Y` pins.
- **Motor Not Turning On/Off Correctly:**
- Verify the relay module is connected to the correct pins on the Arduino Mega.
- Ensure the motor control logic in the receiver code is correctly processing the water level data and triggering the relay.
