/* 
 * This sketch allows to control nicla from a PC.
 * Upload this sketch on an arduino board connected to nicla 
 * through the eslov connector. Then connect the same arduino board
 * to your PC.
 * Now you can use the arduino-bhy tool, written in golang, 
 * to control nicla from either the PC command line or from a web page.
 * 
 * NOTE: if Nicla is used as a Shield on top of a MKR board,
 * please use BHY2Host.begin(true, NICLA_AS_SHIELD)
