One Button + on/off + dim

Projects Programming

Would it be possible to make a flow or write a script where it was possible to use 1 button to control a hue bulb like below. The button has only one flow card “button activated”

Short press = ON / OFF
First long press = Dimming UP
Second long press = Dimming Down

best regards

Yes, it would. What you describe is technically possible.

What do you mean by "flow" and "flow card" ?

Based on his only previous thread, communication isn't very good. May mean Flow Chart?

Herkese teşekkür ederim, Halettim. ihtiyacı olanlar için kodu paylaşıyorum.

const byte buttonPin = 16;
const byte ledPin = 6;
const byte runled = 8;
bool ledOn, dimDown;
int pwmValue = 0;
int i = 0;
int lastvalue;

void setup() {
  pinMode(buttonPin, INPUT_PULLUP);
  pinMode (ledPin, OUTPUT);
  pinMode (runled, OUTPUT);
  digitalWrite (runled,HIGH);
}

void loop() {
  if (!digitalRead(buttonPin)) delay(20);
  if (!digitalRead(buttonPin)) {
    delay(500);
    if (!digitalRead(buttonPin)) {
      while (!digitalRead(buttonPin)) {
        if (dimDown) {
          if (pwmValue > 0) pwmValue--;
        }
        else {
          if (pwmValue < 255) pwmValue++;
        }
        lastvalue = pwmValue;
        analogWrite(ledPin, pwmValue);
        delay(15);
      }
      dimDown = !dimDown;
    } else {
      if (ledOn) {
          
          while (i < pwmValue) {
            pwmValue--;
           analogWrite (ledPin,pwmValue);
           delay(15);

          }
           ledOn = false;
        dimDown = false;
      } else {

          while (pwmValue < lastvalue) {
          pwmValue++;
           analogWrite (ledPin,pwmValue);
           delay(15);

          }

        ledOn = true;
      }
    }
  }

Hello lion1983

It seems to be a school assignment, doesn't it?

If my déjà vu doesn't deceive me, the task has been set before.
