in this tutorial, I am going to show you how to build a wifi controlled smart rover using nodemcu.

with this rover, you can observe the parameters of the robotic surrounding (light, temperature, humidity)in real-time with your smartphone

.first watch this  making video

we are using blynk application to control and read the rover with the help of internet we send data to blink server and blink server will send data to the target device(nodemcu) and vice versa
