The ESP8266 is an awesome SoC (System on a Chip) that can be found on various modules and with different types of firmware pre-loaded. One of these is the ESP-01 which behaves as a WiFi adaptor that is controlled with a neat serial interface and AT commands.
These modules don't arrive with documentation so it's great to see Michael Teeuw's demonstration of how easy it is to connect an Arduino or compatible board to the Internet with an ESP8266.
From getting the hardware connections right through to retrieving time from a remote server, Michael offers a clear and interesting explanation. There's some neat example sketches, hints and tips to get your Arduino onto the Internet in no time at all. To get started, visit Michael's detailed website.

If you're starting out with ESP8266 WiFi serial modules, save time and eliminate risk by using our new ESP-01 WiFi Module shield for Arduino:
Our new shield has a socket that's perfect for the ESP-01 module, and addresses all the needs of the ESP8266 - such as:
- 3.3V regulator dedicated to the module to ensure sufficient current capacity
- Logic level shifters on TX/RX lines: compatible with both 3.3V and 5V Arduino models
- Selectable TX/RX pins: use D0/D1 for hardware serial, or D2 - D7 for software serial
- CH_PD pin on ESP-01 module pre-biased for correct operation mode
- Extra ESP-01 pins broken out for your own connections
- Prototyping area with 5V and GND rails
- All Arduino headers broken out for easy connections
- Stacking R3-style Arduino headers including the ICSP header
So don't fiddle with jumper wires or sub-standard power supplies - order your the Freetronics ESP-01 WiFi Module Shield today. They're in stock right now for only $14 including GST.
