A3144 Hall Effect Sensor

/*
This code uses the digitalRead() function to read the state of the sensor pin. In the setup() function, the sensor pin is set as an input using the pinMode() function.

In the loop() function, the sensor value is read using digitalRead() and printed to the serial port using the Serial.println() function. A short delay is added using the delay() function before the loop starts again.

This code provides a basic framework for reading from an A3144 Hall Effect Sensor using an Arduino. You can modify the code to suit your specific requirements, such as adding threshold values or calculating the frequency of the sensor output.
