Multiple blink on esp8266

Other Hardware LEDs and Multiplexing
1

i clone the setting using millis "//LED1" to "//LED2", means multiple millis but not my expectation.

if only one millis on "//LED1"

  • it can blink on "//LED1" ,1 second blinking, match my expectation
  • work as normal

if two millis on "//LED1" and "//LED1"

  • it can blink on both
  • but not my expectation, blink so fast.

You only have a single global variable named remTime which seems to be used by the millis() timing sections of your code. This will lead to interaction between the timing of each LED

3

may i have some advise?

4

The remTime variable holds the time that the blink started but you use the same variable for each of the LEDs

Use a different variable to hold the start time of each LED

5

tried but same outcome.

You have 4 buttons on your web page. Please explain what each of them should do. For instance, what should happen if 2 or more LED statuses are true at the same time ?

7

pls read my question on #1, please focus on LED1 and LED2 is ok.
LED3 and LED4 is empty.
I only copy LED1 <> LED2 but the LED arnormal.

8

I still don't know exactly what you are expecting the sketch to do

9

This mean that, when led1 button on is clicked, led1 will be blink with millis() as per below.

10

What should happen if 2 of the buttons are clicked ?

11

Good question, if both clicked on, the output seems nearly expect, but have little flashing.
normally, would not clicked on both.

12

I am still confused about what should happen when a single button is clicked. Please explain it in simple words.

If this not correct then please reply with a similar explanation

"When the first button is clicked the LEDs should flash briefly in red every second"

"When the second button is clicked the LEDs should flash briefly in blue every second"

For now, let's leave aside what should happen if two buttons are clicked

Exactly which ESP8266 board are you using ?
I ask because it seems unusual that you are using a pin number of 5 to control the LEDs. Which board have you got selected in the IDE ?

13

Let me try video later

「UKHeliBob via Arduino Forum <notifications@arduino.discoursemail.com>」在 2022年11月7日 週一，18:15 寫道：

14

Why do we need a video ?
Just describe what you want the sketch to do

15

ESP8266 broad

two buttons are clicked Not the point of my question.

My question is how to not delay when clicked on/off on the web.

Maybe my code is wrong, please give some hints.

16

My objective, clicked one of the button on/off to control DATAPIN 5,
when clicked on LED1, blink color red each second
when clicked off LED1, off

when clicked on LED2, blink color blue each second
when clicked off LED2, off
