How to use the wizfi210-- WIFI Arduino Shield.
WizFi210 - WiFi Shield
Introduction
In this tutorial you will learn how to use the WizFi210 - Arduino WiFi Shield with Arduino uno board. This low-cost wifi shield can be easily connected to your WiFi network and communicate with the Arduino uno board through the serial communication protocol. In this tutorial we will control an LED wirelessly from an Android phone/tablet app or from a computer tcp/ip terminal.

Features of WizFi210:
What you will need - Hardware
For this tutorial you will need:
You can also use your phone as a personal hot-spot and connect to it through the following procedure. |
Connect WizFi210 to your WiFi network
Follow the steps below to connect the WizFi 210 with your WiFi network. We will set FizFi210 shield to act as an TCP/IP server.

Hardware configuration:
Connect to WiFi network by using AT commands:
Type and send:
My setup is:
SSID: Xperia M4 with WPA pass: 14539678921
Network IP: 192.168.1.1 and mask: 255.255.255.0
Server address (WizFi210 shield): IP: 192.168.1.150 PORT: 5000
*Android smartphones/tablets have network address 192.168.43.1 so address of our server must be 192.168.43.150.
Note :: Remove RX and TX jumpers from WizFi210 to program your Arduino uno board. After programming,Now put jumpers back to shield with the following connection: RX to TX and TX to RX and set SW to DATA.
To build the circuit, connect one end of the resistor to Arduino pin 12. Connect the long leg of the LED (the positive leg, called the anode) to the other end of the resistor. Connect the short leg of the LED (the negative leg, called the cathode) to the Arduino GND.
The Code ::
******************************************************************************
/* Testing the WizFi210 - Serial WiFi Arduino Shield
*Send A to turn off the LED
*Send B to turn on the LED
*/
const int ledPin = 12;
char data;
int flag=0;
void setup()
{
pinMode(ledPin, OUTPUT);// Set pin 5 as an output
Serial.begin(9600); // Start serial communication
}
void loop()
{
// Check serial connection
if (Serial.available() > 0) {
// read incoming data:
data = Serial.read();
flag=0;
}
// If data is 'A' turn off the LED
if (data == 'A'){
digitalWrite(ledPin, LOW);
if (flag == 0){
Serial.println("LED is OFF");
flag=1; //print this message only one time!
}
}
// else if is 'B' turn on the LED
else if (data == 'B'){
digitalWrite(ledPin, HIGH);
if (flag == 0){
Serial.println("LED is ON");
flag=1; //print this message only one time!
}
}
}
******************************************************************************
Computer TCP/IP terminal
We will use Hercules utility for Windows OS from HW-group to control our led wirelessly, you can download it from here.
Steps - see the image above: |
Android application
Connect your phone/tablet with the same WiFi network and download the "WiFi TCP/UDP Controller" app from Next Prototypes. You can download it from play store (link here) for free. Click the "PREFERENCE" button and set
Well done!
You have successfully completed one more "How to" tutorial and you learned how to use the WizFi210 shield with Arduino uno. What next? You can try to add more leds to your project!
