Finally, after a few months, I finished my Arduino course! For my final project, I put together a car chassis and a robotic arm I had from a previous project. The car has 4 wheels, the robotic arm has 4 servos and it can be controlled remotely via a html page using WebSocket.
To access the remote controller, you can use any smartphone, connect to the WiFi shared from the ESP32, open the website by accessing the ESP32 IP address (which you can see in Serial Monitor).
After I fought my way through working with WebSocket for sending commands from a Html page to ESP32, it was a lot of soldering to make it work together... way more than I expected :) but it was a lot of fun!
To all the beginners who would like to create something similar I would like to recommend an amazing course I followed: Arduino Programming and Hardware Fundamentals
