Arduino IDE + NodeMCU ESP12E ESP8266 + Blynk App | Controlling LEDs and Monitoring Temperature and Humidity with DHT11 Sensor using NodeMCU ESP8266 ESP12E and Blynk App. In this project video I use Arduino IDE 1.8.9 , Notepad++ V7.7.1 , NodeMCU ESP12E ESP8266, DHT11 Sensor, LED and Blynk App V2.27.19 .

Download source code and installation image here : drive.google.com/file/d/1NHGcpH2UG3ktBI_kLOoP6sFbtVw-blxG/view?usp=sharing

The code file is saved in the .rar file format. I created a .rar file using Winrar V5.50, so to extract it, make sure you use the same version of Winrar that I use or the latest version or use the winrar extractor online.

Sorry if my English is confusing, I use an online translator.
