RC Car From Old Parts - Part 1

TL;DR

I’m building an RC car using some of my old electronic parts. Communication is handled by an ESP32-CAM programmed in C++ with ESP-IDF, while the actual car control is managed by an STM32 Blackpill using the STM32 HAL. In Part 2, I’ll show how I modelled and 3D-printed the Audi RS car body and created an autonomous driving system.

Main Highlights

• 📡 ESP32-CAM as a web server, streaming live video and sending driving commands to the STM32F4 Blackpill
• ⚙️ Blackpill managing actuators and sensors, and reporting status (battery, lights, servos, etc.)
• 🔐 Secure communication via REST API + login through DIP (KeyCloak)
• 🔄 Over-the-air firmware updates (FOTA) using the same REST API
