Hola a todos:

Estoy construyendome una botonera de 20 botones y 6 rotarys , para la cual he empezado utilizando un Arduino Leonardo, aprovechando este codigo.Mi intencion es dotar de Bluetooth a la botonera,por lo que he comprado una placa Bluefruit Feather nRf51, pero me veo perdido a la hora de implementar esta funcionalidad.

Alguien me echa un cable? Mil gracias de antemano
