I always worry about my room lamp, specifically how to turn it off because the interrupter is far from me. So I decided to make a small project to control a device, a lamp or whatever I want. I chose to work with ESP8266 and Blynk to make it easier and faster.
Blynk App
You create a new project on the Blynk app and copy your authToken code (example:"bfkdbo3h42d2shgo5223e"), you will found it on the project you made. Paste it into the code that you will upload to the ESP8266. After that you go back to the phone, put a button in your Blynk project and chose the pin you want (example: GPIO5).
