readme contradicts itself on RX-TX connections

Great library, love it, thank you for making it!

Found this contradiction in the readme:

Connect ESP32 GPIO3 (RX) to LD2410 TX
Connect ESP32 GPIO4 (TX) to LD2410 RX

But then the animated diagram shows the opposite - GPIO4 to LD2410 TX, and GPIO3 to LD2410 RX.

Also I'm not sure which ESP32C3 Supermini boards you're using, but all the ones I've found use GPIOs 20 and 21 for RX/TX respectively.

Thanks again for all your hard work!

Also the web interface has a default of 60 LEDs per meter? But doesn't appear I can edit that value? Not sure what that value influences anyway.

The README and animation are both consistent. The connections follow the standard UART cross-connection pattern:

• ESP32 GPIO3 (RX) connects to LD2410 TX
• ESP32 GPIO4 (TX) connects to LD2410 RX

This is the correct way to connect UART devices - transmit pins must connect to receive pins. We're using software serial on GPIO3/GPIO4 rather than the hardware UART pins on some ESP32-C3 variants (GPIO20/21). Also, the "60 LEDs per meter" is a standard WS2812B strip density used to calculate the approximate length of your strip. It's editable but does not make any change for now. When you set the total LED count, it shows you how long your strip would be physically, but doesn't affect functionality.
However, this will be updated.

Just a comment on the "60 LEDs per meter" - I have seen multiple versions with 72 LEDs per meter, especially variants, where the LED strip is inside a silicone tube.
So being able to set/select the numbers of LEDs per meter would be highly desirable.

Updated and added, new version 5.1 released. Each node can run desired LEDLEDs.

@Techposts i try to run with 20 led/m but i do not get on how to set this, i am running 5.1.1.
Any hint?
