Libreria L298N per Arduino

Partiamo con l’esempio più semplice.
Verrà istanziato un solo motore, sfruttando quindi una sola interfaccia del modulo L298N, e gli verranno impartiti dei comandi base intervallati da alcune pause.
/* Author : Andrea Lombardo Site : https://www.lombardoandrea.com Source : https://github.com/AndreaLombardo/L298N/ Here you can see how to work in a common configuration. Speed range go from 0 to 255, default is 100. Use setSpeed(speed) to change. Sometimes at lower speed motors seems not running. It's normal, may depends by motor and power supply.
