Not able to turn blinking on after stopping it.

[wesolykapselek]

Hi.

I'm trying to make a contraption where internal status will be passed to user with 3 LEDs which have to blink. If I turn off the LED I can't turn it on once again. Any suggestions? Device: Wemos D1 Mini.

Edit: Tried multiple options like Reset(), On() and assigning once again new object.

Hi,

On and Off do not start and stop the current effect, they are effects
themselves: if you call Off on a JLed object, then you replace the current
effect (e.g. Blink) with a constant light effect with brightness 0 and period

The same goes when you call On: you replace the current effect with a constant light effect with brightness 255 and period 1.

So after calling On or Off, your Blink effect is gone and I suppose that is what you see.

Try to call Blink(25,975) or someting else again instead of On and see if
this works.

See the documentation for the details: https://github.com/jandelgado/jled#static-on-and-off

This is very kind of you that you responding on Sunday.

Tried two things like: Assigning new object to array with construction like: leds[redLEDindex] = JLed(redBlinkPin).Blink(500, 500).Forever();

Or like you suggesting call Blink or existing array element: leds[redLEDindex].Blink(500, 500).Forever();

Both solutions ends with constant, full brightness light of LED.

Look at this simple example I just tested on an ESP32. Initially it creates 3 blinking LEDs. After 2 seconds, the effects begin to change.

#include <jled.h>

JLed leds[] = {
    JLed(21).Blink(50, 100).Forever(),
    JLed(22).Blink(50, 100).DelayBefore(50).Forever(),
    JLed(23).Blink(50, 100).DelayBefore(100).Forever(),
};

JLedSequence sequence(JLedSequence::eMode::PARALLEL, leds);

void setup() { }

void loop() {
    static int state = 0;
    static int count = 0;

    sequence.Update();

    count++;

    if (count > 2000) {
        count = 0;

        switch(state) {
            case 0:
                leds[0].Off();
                leds[1].Off();
                leds[2].Blink(250,750).Forever();
                state = 1;
                break;
            case 1:
                leds[0].Off();
                leds[1].Breathe(500).Forever();
                leds[2].Off();
                state = 2;
                break;
            case 2:
                leds[0].FadeOff(500).Forever();
                leds[1].Off();
                leds[2].Off();
                state = 0;
                break;
        }

    }

    delay(1);
}

Looking again at your code the problem might be in your loop function, where you change the state of the LEDs over and over again depending on the value of currentFlagStatus.Shouldn't the LEDs only be changes when the value of currentFlagStatus changes?

Damn! You are probably correct! I'm assigning the new object over and over and it can't really kick in!

Your suggestion do the trick! Thank you very much!
