ahhhhh! no, I start from 0 with an example found on the web, the @korttoma sketch is too complicated for me :P

@rejoe2 i use the pullup input and i try in setup to write relayPin to LOW, to put LOW the variable but with no success...

ps: i deleted what??!?!? :P

@rejoe2 ok, i try with succesfully to make a sketch like my initial requests with array function :)

for you is so simply, but for me no! :p

all is ok, only a problem: at boot, at the first pression of one button (pin 27, 28 or 29) put high all 3 output... with another pression of button, all go ok... you see something that i can't see? :) ty

int buttPin[3] = {27,28,29};// you do not want to use digital pins 0 or 1
int relayPin[3] = {30,31,32};
int lastButtState[3];
int buttState[3];
int debounceDelay = 50;
int ledState[3];
int reading[3];
unsigned long lastDebounceTime[3];
    
void setup() 
{
  Serial.begin(115200);
  for (int i = 0; i < 3; i++)
  {
    pinMode(relayPin[i], OUTPUT);
    pinMode(buttPin[i], INPUT_PULLUP); 
  }
}

void loop() 
{
  for (int i = 0; i < 3; i++)
  {
    reading[i] = digitalRead(buttPin[i]);
    if (reading[i] != lastButtState[i]) 
    {
      lastDebounceTime[i] = millis();
      lastButtState[i] = reading[i];
        
    }
    if ((millis() - lastDebounceTime[i]) > debounceDelay) {
       if (buttState[i] != lastButtState[i]) {
           buttState[i] = lastButtState[i];
           if (buttState[i] == HIGH) {
                 ledState[i] = !ledState[i];
                 digitalWrite(relayPin[i], ledState[i]);
  }
  }
 }
}
}```

you are right and sorry

But I search for a simply code for x input and for x relay asking the best method for the code...

now i start from 0 and try simply code! ty

If i trigger the input pin, the output still to LOW

this is the serial code

TDI:TSL
T NODE,CP=RNNNA---,VER=2.2.0
25 TSM:INIT
26 TSF:WUR:MS=0
33 !TSM:INIT:TSP FAIL

37 TSM:FAIL:DIS
38 TSF:TDI:TSL
&"⸮q_⸮⸮!⸮D⸮⸮⸮s⸮ ⸮⸮ED⸮⸮A
Et⸮EE⸮⸮AEň⸮1⸮⸮⸮

uh ok, sorry, i use the first, your right!

now... i have tried this, but always unsuccesfully (i just change the pin)

sorry for tag! :)

this is pratically the code of your link... with some adjustement of my pin configuration... but the output remain LOW...

i know that is not simply :P

Yes, i have try it but unsuccesfull.. this is my sketch

Hi!

I need to control 15 relay with 15 push button (one click on, another click off) on a mega 2560 and w5100.

I want integrate remotexy to control them.

What is the easiest way for that?

Can You help me with the code?

With one button e one relay it's ok (button+remotexy), i dont know how duplicate the code for 15 times with a matrix.

Ty
