In articolul Un modul bluetooth si Arduino am comandat placa Arduino sa aprinda un LED multicolor de la tastatura calculatorului, care avea conectat un "dongle" bluetooth.
Telefonul meu, Allview A4ALL, are instalat un sistem de operare mai vechi, Android 2.3.6 si, de aceea, nu pot instala toate aplicatiile gasite.
Dupa ceva teste, am reusit sa gasesc aplicatia Arduino Bluetooth Controller scrisa de cei de la http://estacado-s-ltd.android.informer.com/
Modulul bluetooth HC-06 l-am conectat ca si in cazul anterior:
Dupa conectarea modulului bluetooth si a celui cu LED-ul multicolor, am activat modul de transmisie bluetoth la telefon, am deschis aplicatia de comanda, am realizat conexiunea cu Arduino si apoi am ales partea cu "Terminal Mode", deoarece am nevoie sa trimit cifre, cum aveam eu in sketch.

- smartphone ca telecomanda prin bluetooth pentru Arduino
19.01.2013
Am modifiat sketch-ul un pic sa "reactioneze" si la litere, adica daca transmit "q" sau "1" sa aprinda LED-ul rosu, daca transmit "w" sau "2" sa aprinda LED-ul albastru, daca transmit "e" sau "3" sa aprinda LED-ul verde, iar la "p" sau "0" sa se stinga toate, vedeti mai bine in filmuletul smartphone ca telecomanda prin bluetooth pentru Arduino (II)
