Android phone controls Arduino over wifi

We recently did a little demo to send data to an Arduino with a TCP/IP Shield (using ATC-1000M) from an Android device via Wifi.

The Android phone in this demo uses Android Scripting Environment (ASE). It is available on Android Market for free.

Videos and source code after the break.

Here is a short video demonstration of blinking the Arduino LED using Android.

#include <SoftwareSerial.h>

#define rxPin 0
#define txPin 1
#define ledPin 13

SoftwareSerial mySerial =  SoftwareSerial(rxPin, txPin);

void setup()
{
pinMode(rxPin, INPUT);
pinMode(txPin, OUTPUT);
pinMode(ledPin, OUTPUT);
digitalWrite(ledPin, HIGH);
mySerial.begin(9600);
}

void loop()
{
char c = mySerial.read();
if(c=='A')
  digitalWrite(ledPin, HIGH);
if(c=='B')
  digitalWrite(ledPin, LOW);
}
