One little chip - game changer! The esp-8266 chip is an amazing little device that offers a 32bit cpu and most importantly wifi built in. Hackers from all around the world have been updating the firmware and now, not only can you use the original AT command structure (think modem commands), you now have a fully featured bios that can run Lua, arduino, basic and more!
Why is this a game changer - one reason - PRICE!! This chip can be purchased on eBay right now for as little as $2 for an esp-01 up to a high price of about $7 for an esp-12 (nodemcu with an integrated usb converter for programming)! Needless to say - this is DIRT CHEAP for the functionality/usability you get!
I've pretty much decided to flash nodemcu to all my esp8266's I get so most, if not all, of the projects featured here will use nodemcu firmware which is coded in Lua. Right now I've got ESP-03 chips (on breakout boards), and some ESP-12s in stock as well as a bunch of random sensors from eBay (sound, light. vibration etc.).
Thanks for looking and hopefully we learn something together with these!
