The WiFi Shield was delivered by Amazon.
The Arduino UNO Rev 3 was found at RadioShack…
First you need to load the last Arduino IDE (Ver 1.0.2) it has the necessary library to use the WiFi shield.
Tried the examples “Scan for available networks” and “WPA network example”
from:
http://arduino.cc/en/Guide/ArduinoWiFiShield
It works like a charm!
thanks Arduino Team…
Now some work is comming…
Thinking in some applications…
Here is the code:

LaunchPad and Energia ( StopWatch )
This is a simple project using the LaunchPad from Texas Instruments and Energia (Arduino-like IDE).
The Launchpad version 1.5 comes with the MSP430G2553 microcontroller, it has a hardware UART (use the jumpers as shown in the image).
This is a funny and very low cost project.
The LaunchPad measures time (in microseconds) .The car travels a fixed distance between contacts (10 Cms).
Time is measured using START and STOP contact switches.
Contact switches are implemented using neodymium magnets.
You’ll need small nails, miniature neodymium magnets and colors headed pins to assemble the switches.
Here is the code used:
/* Cronometer01.ino
Arduining.com 25/AUG/12
Used in the LaunchPad V-1.5 with the MSP430G2553
Measuring time between the signals of START and STOP in microseconds.
The result is sent serial at 9600 bauds.
GREEN LED on indicate READY TO START.
RED LED on indicate MEASURING TIME.
RED LED blinking indicate MEASURE DONE.
Push RESET in the LaunchPad to repeat the measurement.
*/
#define START 11 //Pin P2.3
#define STOP 12 //Pin P2.4
unsigned long time;
void setup() {
pinMode(START,INPUT_PULLUP); //internal pull-up
pinMode(STOP,INPUT_PULLUP); //internal pull-up
pinMode(GREEN_LED, OUTPUT);
pinMode(RED_LED, OUTPUT);
Serial.begin(9600);
}
void loop() {
Serial.println("READY");
digitalWrite(GREEN_LED, HIGH); // set the GREEN LED on
digitalWrite(RED_LED, LOW); // set the RED LED off
while(!digitalRead(START)){}
time = micros();
digitalWrite(GREEN_LED, LOW); // set the GREEN LED off
digitalWrite(RED_LED, HIGH); // set the RED LED on
while(!digitalRead(STOP)){}
time = micros()-time;
digitalWrite(RED_LED, LOW); // set the RED LED off
Serial.print(time);
Serial.println(" Microseconds");
while(1){ // Blink to indicate END.
delay(900); // wait 0.9 second
digitalWrite(RED_LED, HIGH); // set the RED LED on
delay(100); // wait 0.1 second
digitalWrite(RED_LED, LOW); // set the RED LED off
}
}
