This is the HC-SR04 ultrasonic ranging sensor. This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. There are only four pins that you need to worry about on the HC-SR04: VCC (Power), Trig (Trigger), Echo...

Step 1. Implement the function reading your sensor Basically all that you need to do in your arduino code is implement a function that reads your sensor and returns an angle in radians between 0 and 2π: floatreadMySensorCallback(){// read my sensor// return the angle value in radians ...

The steps of using this library in code are very similar tohardware interrupt. The SimpleFOCHallSensorclass still provides you with all the callbacksA,BandCchannels but the Simple FOC library will not initialize the interrupts for you.
