Blink Clock dots with rainbow effect

Projects General Guidance
1

I made a Neopixel clock with rainbow effect its working fine but without flashing dots. I make display 148 leds, 5 leds per segment *7 +2 leds for dots Total 37 leds for each digit.
I want to blink dots. This is my sketch.

#include <Adafruit_NeoPixel.h>

Adafruit_NeoPixel strip = Adafruit_NeoPixel(148, PIN, NEO_GRB + NEO_KHZ800);

void setup() {
// Setup the LED strip and RTC module.
strip.begin();
strip.show();
rtc.begin();
}

void loop() {
// Cycle the clock digits through rainbow colors.
rainbowCycle(100);
}

/* (Methods to un-set certain LEDs to form 7-segment digits.) */

void unsetTimeDigits() {
DateTime now = rtc.now();
flip_digits(now.hour() / 10, now.hour() % 10, now.minute() / 10, now.minute() % 10);
}

// First digit.
flip_digit(111, d1);

Welcome to the forum

Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'

Use [color = red]code tags[/color] (the < CODE/ > icon above the compose window) to make it easier to read and copy for examination

https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum

In my experience the easiest way to tidy up the code and add the code tags is as follows

Start by tidying up your code by using Tools/Auto Format in the IDE to make it easier to read. Then use Edit/Copy for Forum and paste what was copied in a new reply. Code tags will have been added to the code to make it easy to read in the forum thus making it easier to provide help.

I highly recommend looking into arrays and loops. If you use arrays and loops, your program will become several times smaller and better understood.

Would you draw a picture? I can imagine a 5x7 character, but not "two dots" per character.

Where's rainbowCycle() (your main program)?

5

The colon between digits maybe ?

6

That makes sense, but "two per digit?"

7

Two dots equals one colon ?

8

I can see one colon, but each digit? Does OP numbers use umlauts?

"5 leds per segment *7 +2 leds for dots Total 37 leds for each digit."

I have the WOKWI barbi fired up... waiting for the missing function (rainbowCycle)

You are right... every number has a two-dot colon. LEDs are:

  0 -  34 +  35,  36
 37 -  71 +  72,  73
 74 - 108 + 109, 110
111 - 145 + 146, 147
