Summary of Arduino Wifi Shield is back on the store!
The Arduino WiFi Shield enables wireless internet connectivity for Arduino boards via the 802.11b/g standard. It utilizes an HDG104 chip and an Atmega 32UC3 processor to manage TCP/UDP network stacks. Compatible with Uno and Mega boards, it features a microSD slot for file storage and uses long wire-wrap headers to maintain pin layout for stacking additional shields.
Parts used in the Arduino WiFi Shield:
- Arduino Board
- Arduino WiFi Shield
- HDG104 Wireless LAN 802.11b/g System in-Package
- Atmega 32UC3
- WiFi Library
- Long wire-wrap headers
- Onboard micro-SD card slot
- SD Library
Overview
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.
Description
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 HDG104 Wireless LAN 802.11b/g System in-Package. An Atmega 32UC3 provides a network (IP) stack capable of both TCP and UDP. Use the WiFI library 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.
