WIFI Control Car With ESP8266 And Blynk2.0 App

ESP8266 And Blynk2.0 App Robot Car

Introduction 

Hi Everyone, In this Tutorial, we will make a wifi-based control car Based on the New Blynk2.0 App. Nowadays day Robotics technology is used in various fields new designed Come to day by day.

Mostly wi-fi networks were using various applications. The various applications are done by robot cars like IOT IOT-based grass Cutters, IOT-based firefighters, IOT-based wheelchairs, and IOT-based agricultural robot cars.

in this Article, we will discuss how you set up the Blynk app and interface the l298n motor driver to ESP8266. With the help of this article, you make many Robot Car Projects.
