Introduction: Arduino Wifly Shield Tutorial
There are many things you can do with your arduino board. For instance, you can add wifi connectivity to your project. To do this, you need an Arduino Wifly RN-131C shield or any other type of WiFi shield you can get in the market.
The arduino Wifly shield comprises of the Roving Network’s wireless module RN-131C and SPI to UART chip. It is powered from the Vin pin of the arduino and communicates with the arduino through digital pins 10 (CS), 11(MOSI), 12(MISO) and 13(SCLK). Normally, the Wifly RN-131C shield does not come with pins. Therefore you have to solder them onto it. You should solder pins onto TX, RX, 10, 11, 12, 13, Vin and GND as shown in the photo. Ensure you solder them carefully so as to avoid joining any of the pins together.
Once you are through mounting the Wifly shield on the arduino board, you can start coding it. There are several things you can do with you Wifly module. For instance, you can create a Wifi hotspot to enable other devices such as your smartphone, tablet or computer to wirelessly control your project. Moreover, you can use the Wifly module to join other Wifi networks and allow you to control your project using the internet.
