Arducopter led ON/OFF on a remote switch

Hello,

Am building a fpv long range cruiser. I am using 2 single ws2812 leds. Flight controller am using is Holybro kakute H7 mini. One led i have soldered on the led pad and it shows me the status of the board and changes color on arming and disarming.

My problem is the second led which i have put on the M8 pad and wants that led to switch On and Off via remote switch and when ON it should glow white at full brightness.

This i am not able to do. I don’t know how to use lua script.

If anyone can help, that will be great.

Thanks in advance.

Regards,
Rahul
