Hi @pavanesleeba,

You can use the timeout function.

<button onclick="led_on()">ON</button>
<script>
function led_on(){
  digitalWrite(0, 'HIGH');

  setTimeout(() => {
    digitalWrite(0, 'LOW');
   }, 30000);
}
</script>

Do let me know in case you need further assistance.

Hi @pavanesleeba,

You can not add timeout function in Dualbutton class, but you can write your javascript function to do that.

add the code below:

button = document.createElement("BUTTON");
button.classList.add("btn");
var text = document.createTextNode("On");
button.appendChild(text);

button.onclick = function() {
    digitalWrite(0, 'HIGH');
    setTimeout(() => {
        digitalWrite(0, 'LOW');
        
    }, 30000);
    
};

document.body.appendChild(button);
