Digital clock with Arduino, 128x64 LCD display and RTC module DS3231

The best projects with Arduino, Raspberry Pi, ESP8266, IoT (Internet of Things), sensors and modules. Check out the Arduino e Cia blog at www.arduinoecia.com.br
Build a watch that shows the hours and the room temperature at the touch of a button!
This project uses an Arduino Uno board, a 128x64 LCD graphics display, and a high-precision Real Time Clock (RTC) module DS3231 which also has a built-in temperature sensor. In the display, we show the time in both analog and digital format, the current date and the maximum and minimum temperatures.
The complete project with the program, circuit connection scheme and other information you can find at www.arduinoecia.com.br/2015/1...

Thanks for reply
I already done this
I appreciate your valuable support

Bom trabalho, estou interessado em seguir seus passos, mas a verdade é que sou novo nesse aspecto. Seria possível incluir esp8266 com o protocolo MQTT para monitoramento de temperatura?

Oh beautiful. Thanks a lot for the tutorial.
Dear respected sir, I need to increase the front size of the digits in 128X64 size LCD but I don't know how to do it. Do need to install any library?
Please could you help me?

Your video is great, I also want to make a simple digital clock. Although there is a test box, I will not program now. Can you teach me?

Como adiciono um botão no relógio que você fez, professor, por favor

[@ArduinoeCiaMaker]

Opa! Pois é, faltou essa função.. quem sabe numa próxima versão do relógio... :) Abraço!

Dear Friend,
I found your project, it is nice and very useful...I have one question, could you please help
with the existing only two modes are in the code as below;
u8g.firstPage();
do {
if (estado_botao == 0)
{
tela_1();
}
if (estado_botao == 1)
{
tela_2();
}
}
while( u8g.nextPage() );
delay(10);
I want to add two more like tela_3(); and tela_4();
could you please tell me how to do
thanks in advance
