Current sensing applications and automotive industry

Interfacing Hall Sensor with Raspberry Pi to detect – ( Also provide a practical context to the propose project (measure field leakage of a magnetic source?* and also add some interactions, for example attach 5 LEDs to indicate the strength of the magnetic field. *Attach a buzzer to produce note (increasing pitch to higher magnetic fields)

The following components/parts are required to build this project; Add challenges and fallback plan
