This website provides free electrical & electronics projects with circuit diagram and source codes. Cuando tenemos un módulo como el NodeMCU que puede conectarse a Internet mediante WiFi, lo primero que se nos puede ocurrir hacer con él es acceder a datos en la red. The objective of this post is to explain how to use the ESP8266 library defined constants that have the correct mapping between NodeMCU and ESP8266 pins. In our shop, we also develop a WiFi smartcar, which can be controlled by mobile, PC, and wechat (now just in China). I am using an ESP8266-12E-Devkit from Aliexpress (NodeMcu Lua ESP8266 ESP-12E WIFI Development Board (SKU256450) EUR 8. And it is very low cost.
