Добрый день! Я снова к вам с просьбой. Можете, пожалуйста,внести поправку в коде так, чтобы при включении часов, перед тем как высветится время, включался перебор цифр.

Добавил код в setup не уверен что будет работать:

Добавил код в setup не уверен что будет работать:

Да, что-то не хочет работать...

И еще такой вопрос, использую режим день-ночь, и заметил что немного не совпадают установленные значения. к примеру, дневной режим у меня стоит на включение в 9-00, а включается он только в 10-00, т.е. разница с настройками 1 час.
Заранее спасибо.

Возможно что то в этом коде не то:

if(hh>=0&&hh<=end_night||hh>=start_night){ledcWrite(2, 255-brignes_low); }else {ledcWrite(2, 255-brignes);}

может исправить на

if(hh>=0&&hh<end_night||hh>=start_night){ledcWrite(2, 255-brignes_low); }else {ledcWrite(2, 255-brignes);}

Добрый день! Я снова к вам с просьбой. Можете, пожалуйста,внести поправку в коде так, чтобы при включении часов, перед тем как высветится время, включался перебор цифр.

Добавил код в setup не уверен что будет работать:

Для авторизации в сети Wi-Fi переводится в режим точки доступа с фиксированным IP адресом — 192.168.4.1 , для перевода ESP32 в режим точки доступа необходимо на пин D23 подать GND (нажать фиксированную кнопку AT/STA) и нажать кнопку RESET (или отключить и снова включить питание).

Других вариантов не вижу, должно работать.

Есть еще один странный глюк, который проявляеться не всегда.

Вроде и это победил.
Сделал как вы советовали ранее:
Если имеются проблемы, то перенесите этот код в начало setup()

///////// PWM IRF840 //////////////////
  ledcSetup(2, 25000, 8); // 25000 kHz / 8 bit / cannel 2
  ledcAttachPin(15, 2);   // D15 / cannel 2
  ledcWrite(2, 255-brignes);

Да, подойдет.

День добрый.
А вот такой модуль подойдет?

У меня нет возможности провести полное тестирование, но тестовый скетч работает правильно

long ms,stop_ms,sum,times1,ss,times0;


void setup(){
  Serial.begin(9600);
  }

void loop(){
if(millis()-times1>50){ms++; times1=millis();}
if(ss==59){ms=0;}
if(ms<=9){
switch(ms){
    case 0: sum=000000;break;
    case 1: sum=111111;break;
    case 2: sum=222222;break;
    case 3: sum=333333;break;
    case 4: sum=444444;break;
    case 5: sum=555555;break;
    case 6: sum=666666;break;
    case 7: sum=777777;break;
    case 8: sum=888888;break;
    case 9: sum=999999;break;}
Serial.println(sum);}


if(millis()-times0>1000){times0=millis();ss++;if(ss>59){ss=0;}} // отсчет секунд

}

Все победил))
Скетч поправил, сделал себе выбор перебора каждую минуту или каждые пять минут. А чтобы засветы убрать допаял стабилитроны BZV55-C75 по прикрепленной схеме. Лампы стоят ИН-8.

if(millis()-times1>50){ms++; times1=millis();}
if(ss==59){ms=0;}
if(ss<10&&ms<=9){
switch(ms){
    case 0: sum=000000;break;
    case 1: sum=111111;break;
    case 2: sum=222222;break;
    case 3: sum=333333;break;
    case 4: sum=444444;break;
    case 5: sum=555555;break;
    case 6: sum=666666;break;
    case 7: sum=777777;break;
    case 8: sum=888888;break;
    case 9: sum=999999;break;}
}

Ругается на скобки в конце. Если ставлю двойные, то код компилируется, но все равно после загрузки только один раз переберет цифры и все.
