Range finder (Part 2)

Part 1, 2 As in most arduinoos posts, the examples given here differ from what is usually seen and read in terms of  code efficiency  and ruggedness of applications. Early tests performed on the HC-SR04 module proved its easiness of setup and interesting results obtained from scratch. However things are changing when accuracy is concerned and headaches […]
