Servo motor vs. DC motor: sound comparison

The sound volume was compared between a servo motor and a DC motor as a mechanism to move the mouth of a talking robot.The DC motor was connected to an ESP32 using an L293D motor driver, and the gears to be attached were made using a 3D printer. The rack and pinion moves by itself, but not when a rubber is attached.

[ESP32] How to migrate from Arduino IDE to Platform IO

After switching from Arduino to PlatformIO, I can now use VSCode to centralise all code creation, Build and Upload, and I feel that the Build speed is about twice as fast as with Arduino. It's also good that it automatically searches for ports.

[ESP32 x PlatformIO] How to coexist the framework with Arduino and ESP-IDF

PlatformIO allows the Arduino and ESP-IDF frameworks to be used together: by setting framework = arduino, espidf in platform.ini, many existing Arduino libraries can be used directly, thus reducing the need for code porting This saves time and effort in porting and rewriting code.
