Smartphone ca telecomanda prin bluetooth pentru Arduino

   Dupa ce am intrat in posesia unui smartphone (telefon cu Android), am zis sa comand un Arduino conectat la un modul bluetooth cu ajutorul acestuia.
   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.

 

 

 

 

 - am apasat "tasta" 1 si s-a aprins LED-ul in rosu:

 - am apasat "tasta" 2 si s-a aprins LED-ul in albastru:

  - am apasat "tasta" 3 si s-a aprins LED-ul in verde:

   Sketch-ul folosit de mine este:

   Am facut si 2 filmulete:
- smartphone ca telecomanda prin bluetooth pentru Arduino

- smartphone as bluetooth remote for 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)
