LM393 Angle Inclinometer Sensor

/*
This code reads the angle from the LM393 Angle Inclinometer Sensor and prints the result on the Serial Monitor of the Arduino IDE. The analog value from the sensor is converted to voltage using the formula voltage = sensor_value * (5.0 / 1023.0), where 5.0 is the voltage of the Arduino's power supply and 1023 is the maximum analog value. The voltage is then converted to angle using the calibration curve of the LM393 sensor, which maps the voltage range of 0V to 5V to an angle range of -90 degrees to 90 degrees.

To use this code, connect the LM393 Angle Inclinometer Sensor to an analog input pin of your Arduino board (usually A0 for most Arduino boards), and connect the sensor power supply and ground to the corresponding pins of the Arduino board. The sensor should be powered with a 5V DC power source.

Note that the accuracy of the angle measurement can be affected by various factors, such as the temperature and humidity of the environment, and the calibration of the sensor. You may need to adjust the calibration curve of the LM393 sensor to improve the accuracy of the angle measurement.
