The following steps need to be taken:

1. Download the Blynk Mobile App

2. Look up the Blynk Website and figure out way to use Blynk with Esp 32

3. Set up a Project and include 2 Joystick widgets

4. Configure the Virtual Pins of Widgets and read their values in the program written in Arduino IDE

If you want to skip the process, download the program given in the link below.

Assemble the Car

Cut a square out of plywood and add all the parts step by step.

Connect the battery and the robot is ready to run.
