My RC car works

 Here is what I done with regards to learning and building RC controlled car, whether automomous, Wi-Fi controlled or bluetooth controlled or any RF system. 

The first rc car I built is the bluetooth Arduino based RC car which is controlled using a mobile phone. The video showing this car is below.

Then I built the NodeMCU WiFi RC car which is demonstrated in the following video.

Then I built the autonomous robotic car which is demonstrated in the following video.
