The wiring diagram below shows how to connect everything that way. Next, if you use the same ESP32 microcontroller Marzen used, be sure to cut the thin wire in the middle of the low-power pad ...

It’s still an ESP32, but one that’s more useful, and it’s worth a closer look because we expect it to figure in quite a few projects. Espressif’s block diagram for the chip. Sadly the data ...

For those looking to upgrade their kid’s ride, [David] has provided source code for the ESP32, a parts list, a wiring diagram, and even the 3D models for the few parts that needed to be printed.
