here is an example of how to do communication over UDP, while sending the status of the 5 pins is enough with a byte-type variable, there will still be space for 3 bits, each bit denoting a different button.

Thanks for the hint. When my PRC tiles arrive I will upload what you suggested. Unfortunately the current boards were damaged by my son. In the meantime, I will read about diode lighting .

I have finally received the plates. I managed to do what I set out to do. There were some problems with the code. One worked incompletely, another hung up every now and then. I managed to upload the code and modify it slightly. . [/film].

Hello...
I need those experienced in this subject to help me solve a problem.
I have five momentary buttons. When any one or more of them were pressed on the first nodemcu it was signalled remotely via my own wi-fi or home network on the second nodemcu board with leds.
For those unfamiliar with these boards, it's certainly a breeze.
