A simple Arduino program to access the retro.hackaday.com site via an ESP8266 serial wifi module.
Contains fairly detailed instructions for getting things working on an Arduino Mega 2560 with a version 2 module and notes on what has changed since the Seed Studios tutorial was written (for the version 1 module).
I've tried to avoid calls to delay() where possible, as these tend to do more harm than good: the default Arduino hardware serial buffer is only 64 bytes. (See SERIAL_BUFFER_SIZE in HardwareSerial.cpp)
I tried this using my arduino uno and softwareserial instead of serial1, but it didn't wok. The Get just doesn't return anything. It says SEND OK, but no more.
I also ran the AT commands directly through RX TX connected but the same. The get statements fail for some reason. I read about flashing the esp8266 and replace the firmware for the nodemcu, so I ordered the usb 2 serial...
