How to Set the Brightness with the timing for NeoPixel ring

Hi All

I need some help on this, what is the code I should use I want to set the brightness
for example, if I want to get the time between 11 PM to 7 AM at maybe brightness level at 50 and from 7 AM to 10 PM as 120

I try to get the code as below but it seems to work but not as what I need, I'm not sure how can I get in between the timing code.

if (hr > 23);
pixels.setBrightness(20);

and how can I also get the function for day of week
for example, today is Sunday and the color will be shown as red.

#include <Adafruit_NeoPixel.h>
#define PIN 6 // DataPIN on Arduino Uno
#define NUMPIXELS 12 // Total Number of Pixels for Clock

// Date and time functions using a DS1307 RTC connected via I2C and Wire lib
#include "RTClib.h"

// Define DS1307 RTC
/*
*

  • PINOUT : GND,5V,SCL=A5, SDA=A4 of arduino
    */

RTC_DS1307 rtc;

char daysOfTheWeek[7][12] = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};

Adafruit_NeoPixel pixels(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);
// Arduino Library Use | Adafruit NeoPixel Überguide | Adafruit Learning System
// Argument 1 = Number of pixels in NeoPixel strip
// Argument 2 = Arduino pin number (most are valid)
// Argument 3 = Pixel type flags, add together as needed:
// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)
// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
// NEO_RGBW Pixels are wired for RGBW bitstream (NeoPixel RGBW products)

Oops.

pixels.setPixelColor(6,(hr=6)?white:green);

And again

if (hr > 23);

And another.

Hi sorry, I'm a first-time posting here.

That's not really an excuse when just about every significant section of the forum (including this one) has this topic in it

This doesn’t mean you cannot edit your post and format the code properly
