ESP32-Cam Car

One of my favourite makers - Bill in his Dronebot Workshop published a ESP32CAM Robot Car project in 2021. I followed and built one which was working well. But after some years, the codes do not work due to the updated ESP32 boards that removed some AI functions for the ESP32CAM modules. Therefore, I debugged and edited the codes (with the help of ChatGPT) to create a working version for this car. This version also fixed some issues in its web interface. If you have also built one (with same wiring), then you could download my codes below (but still double check the wiring) to make it work.

In this version, the main components of ESP32Cam board and TB6612FNG H-Bridge controller are the same but I used two-14500 batteries instead of 18650 because I have a smaller chassis, and I used a different buck converter to step down the 7~8V from the 14500 batteries to 5V for the ESP32Cam.
This projects demonstrated the Wifi wireless communication in remote controlling. In other projects, we have also demonstrated in the remote car context using:
Infrared communication is another common wireless communication in real-world but because of its directional communication, it is not ideal for controlling a car that moves and changes orientations.
The ESP32Cam is getting old but it is a very affordable microcontroller with a camera. I have also used it as a monitoring camera for projects such as the IoT: Plant Environment Monitoring project, or you could visit the ESP32Cam for projects page to see how to easily setup one for project.
