Arduino Remote Control using Phone Bluetooth.

To see how to use this App click here. It is tutorial with a sample project. You can use the App for your own projects.

For this App to work you need to put a Arduino sketch in your Arduino device. To download the Arduino Sketch click here.

Learn various Arduino Commands by Chatting with Arduino. Program and set Arduino Pin functions by sending commands remotely without downloading code.

App is used to program (change pin settings) of Arduino remotely using Bluetooth. You do not need to download programs to change pin settings like pin mode. You can do it remotely using this app.

Its a great tool to learn Arduino in the most fun way by chatting with Arduino.

You can use the sample sketch given here. This sketch can be customized/changed to suit your needs, language and enhance your experience.

Per vedere come utilizzare questa app, fai clic su qui. Esercitazione con un progetto di esempio. Puoi usare l'app per i tuoi progetti.

Per far funzionare questa app è necessario inserire uno schizzo Arduino nel dispositivo Arduino. Per scaricare lo schizzo di Arduino, fai clic qui.

Impara i vari comandi di Arduino chattando con Arduino. Programmate e impostate le funzioni di Arduino Pin inviando i comandi da remoto senza scaricare il codice.

App viene utilizzata per programmare (modificare le impostazioni dei pin) di Arduino da remoto tramite Bluetooth. Non è necessario scaricare programmi per modificare le impostazioni dei pin come la modalità pin. Puoi farlo da remoto usando questa app.

È un ottimo strumento per imparare Arduino nel modo più divertente chattando con Arduino.

È possibile utilizzare lo schizzo di esempio fornito qui. Questo schizzo può essere personalizzato / modificato in base alle tue esigenze, lingua e migliorare la tua esperienza.
