Why flash your ESP8266 module with NodeMCU?

NodeMCU is a firmware that allows you to program the ESP8266 modules with LUA script. And you’ll find it very similar to the way you program your Arduino. With just a few lines of code you can establish a WiFi connection, control the ESP8266 GPIOs, turning your ESP8266 into a web server and a lot more.

ESP8266 WiFi Module, in it’s default configuration, boots up into the serial modem mode. In this mode you can communicate with it using a set of AT commands. I will present to you a reference of all known AT commands that ESP8266 supports, explain what they do and how to use them.
Historically AT commands are based on the Hayes Command Set and these are no different.

Although I find the whole concept of the Great Ball Contraption fascinating, I have to admit that I have not been particularly tempted to build one myself in the past. I can’t say for certain why this was so, save perhaps that I saw too many versions of the standard conveyor built with tracks. Then Akiyuki started creating modules and posting YouTube videos and I was blown away. He has not only created some of the most mechanically complex LEGO creations ever, but he has managed to make them beautiful and mesmerizing at the same time. My favorite of these is the Ball Factory, a stunningly complicated mechanical creation powered by only a single motor. This model not only performs the standard GBC function of moving balls from left to right, but also integrates a similar system of moving buckets which is seamlessly integrated with the ball functions. See for yourself.

You want to make a cool robot, maybe a hexapod walker, or in my case I want to use 9g Micro Servos to switch the points on my LEGO Train Layout I’m constructing. Or maybe you want to drive a lot of LEDs with precise PWM output. Then you realize that your Raspberry Pi only has a single PWM output on GPIO-18! What now?
