Let's Learn NodeMCU(EPS8266MOD) very popular IoT component
NodeMCU SETUP GUIDE WITH ARDUINO These days IoT applications are so popular. And I think you have seen my previous posts about IoT Greenhouse. There I tried to pull out many concepts about IoT Technology. http://akilacollection.blogspot.com/2016/05/iot-greenhouse-project-part-3.html There we have used some cost methods for IoT client Eg (Arduino Uno + Wifi Shield). But using this NodeMCU model you can reduce your cost much and this is low power consumption and integrated networking to the module So let's learn about this. The ESP8266 WiFi Module is a self-contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your Arduino device and get about as much WiFi-a
