An ESP32 Delivers Perfect Slot Car Control
If you remember slot cars as simple childhood toys, you’ll be amazed by the technological advancements in competitive slot car racing today. Maker Fabio has taken this beloved hobby to the next level with a sophisticated controller powered by an ESP32 microcontroller.
This cutting-edge controller features a meticulously designed build, both physically and in its software. The trigger operates on a proper bearing, with a Hall-effect sensor on the PCB providing precision control. Fabio wrote the firmware using the Arduino IDE, and the controller’s settings, including speed curves and braking, can be customized for each car via a rotary encoder and an OLED display. The result is a highly adaptable unit that allows racers to tweak settings in real-time.
The hardware and software files will be released once the project is finalized, but the demonstration in the video already highlights the impressive capabilities of this modern slot car controller. For enthusiasts, this project represents the next evolution in slot car racing, blending electronics and customization for a more competitive edge.
