Blinking your onboard LED with a special beat to make sure you played with the MCU and that you were able to successfully use the MCU before, stop yourself from doubting whether you had overcame any problem like driver, bootloader, etc. before and able to use the MCU normally.
It's tested on an ESP32-C3 SuperMini, and it seem to be active-low. Feel free to invert the output from LOW to HIGH, HIGH to LOW by yourself.

Of course, I know I can use milis() to avoid blocking, but... it's just another blink
