EEPROM Issues The ESP8266 doesn’t have a true EEPROM. But the Arduino software emulates it with flash. When you want to use the EEPROM you have to inform the library how much memory you will use.

No matter what type of connection you choose – Ethernet, Wi-Fi or maybe this new ESP8266 everyone is talking about – Blynk libraries and example sketches will get you online, connect to Blynk ...

Support for Spark Core and ESP8266 is also planned. Blynk is on Kickstarter now seeking $10,000 and has raised over $15,000 with 18 days to go.

Blynk uses drag-and-drop widgets to help you control various parts of your electronics projects. This could mean LED values, servo speeds, or just checking in on a variety of data.

You usually think of using Blynk with an Arduino, but you can also program the embedded part directly on an ESP8266. I quickly threw together a little prototype joystick.
