ESP8266 as WiFi for Arduino I have a pretty simple project, where some data has to be read from a mySQL server. My idea is to do this with an ESP8266, and then provide that data to the Arduino Mega.

Is this possible or am I going to have to use the ESP8266 itself? I highly doubt that I would have enough pins then.

I read something about AT-commands. But I have no idea how to send those commands to the ESP.

Thanks in advance,

Check out ESP-LINK You can find it here
ESP-LINK is a esp8266 wifi-serial bridge, outbound TCP, and arduino/AVR/LPC/NXP programmer. It has several configuration, one of them allowes uploading new firware ower wifi, or to act as a serial link just like if usb cable is pluged in and serialport viewer is active. The website has great documentation and has one of the slickest configuration interfaces seen on ESP.
