Hello. Did you try LED example?

Hai Yes and al other examples. The problem is that you do not do any programming when i am using the button in the app. But some time the app stop or has a delay.I want to check if the digital output on the arduino is high or low But i simply do not find that answer. think as a loop back in this way.

You could use next code

WidgetLED led1(V1);
...
if (digitalRead(inPin)) {
    led.on();
} else {
    led.off();
}

You need a code in that case. Either use value display instead of LED.

Hai
as a beginner i understand part of your code. Do i not need to declayer the ( inpin)?

or should i place the digital D6 in there? if so how is the digital D6 called in c++
i have the WidgetLED led6(6); line put in whit succes
relay 0 has button D6 and LED V6
relay 1 has button D7 and LED V7
relay 2 has Button D8 and LED V8
ect…
If i tab on button D7 the digital has a High o then arduino and the relay switsches. I would like that the LED V7 is than on and isoff when the relay button is also off. I
