Arduino Wifi Shield Ad Hoc Network

DFRobot WiFi Shield for Arduino, is part of our wireless family product. This WIFI Shield V3 supports AP + STA dual mode, and is extremely easy to connect to a home router network.

Reference WiFi library The firmware for the WiFi shield has changed in Arduino IDE 1.0.5. You are recommended to install this update per With the Arduino WiFi Shield, this library allows an Arduino board to connect to the internet. It can serve as either a server accepting incoming connections or a client making outgoing ones. The library supports WEP and WPA2 Personal encryption, but not WPA2 Enterprise. Also note, if the SSID is not broadcast, the shield cannot connect. Arduino communicates with the WiFi shield using the SPI bus. This is on digital pins 11, 12, and 13 on the Uno and pins 50, 51, and 52 on the Mega.

On both boards, pin 10 is used as SS. On the Mega, the hardware SS pin, 53, is not used but it must be kept as an output or the SPI interface won't work.

Digital pin 7 is used as a handshake pin between the Wifi shield and the Arduino, and should not be used. The WiFi library is very similar to the library, and many of the function calls are the same.

The Arduino WiFi Shield connects your Arduino to the internet wirelessly. Connect it to your wireless network by following a few simple instructions to start controlling your world through the internet.

As always with Arduino, every element of the platform – hardware, software and documentation – is freely available and open-source. This means you can learn exactly how it's made and use its design as the starting point for your own circuits.

OSH: Schematics Arduino WiFi Shield is open-source hardware! You can build your own board using the following files: The Arduino WiFi Shield allows an Arduino board to connect to the internet using the 802.11 wireless specification (WiFi). It is based on the Wireless LAN 802.11b/g System in-Package. An AT32UC3 provides a network (IP) stack capable of both TCP and UDP. Use the to write sketches which connect to the internet using the shield. The WiFI shield connects to an Arduino board using long wire-wrap headers which extend through the shield.

This keeps the pin layout intact and allows another shield to be stacked on top. The WiFi Shield can connect to wireless networks which operate according to the 802.11b and 802.11g specifications. There is an onboard micro-SD card slot, which can be used to store files for serving over the network. It is compatible with the Arduino Uno and Mega. The onboard microSD card reader is accessible through the SD Library. When working with this library, SS is on Pin 4. Arduino communicates with both the Wifi shield's processor and SD card using the SPI bus (through the ICSP header).
