DS1307 RTC module With Arduino (Tiny RTC ).

This is a detailed explanation of the hardware structure of the DS1307 RTC and how to use this Real Time Clock with Arduino. I also demonstrate how to display time and date on an I2C LCD.

very detailed and clear, thank you

[@Ayesha86_]

you used the 2032 non li rechargeable battery? If so then wouldnt you remove the charging circuit from the ds 1307 because that will force the battery to charge and can cause it to explode.

Bom dia amigo. Muito bom seu projeto, bem explicativo e pratico. Parabéns. Vc poderia me dar um auxilio? Tenho um módulo de 8 relés e um rtc ds1307. Programei um horário para ligar o módulo, porem gostaria de ligar cada um dos relés em 1 minuto após o outro. Tipo ligo todos juntos as 12:00 e desligo um por minutos tipo 13:00, 13:01, 13:02, 13:03, 13:04, 13:05, 13:06, 13:07, 13:08. Teria como me dar um auxilio? Agradeço desde ja

The sketch for the LCD has all kinds of errors in it! I had to edit the line for LiquidCrystal_I2C to say " LiquidCrystal_I2C lcd(0x27, 16, 2);".

Is it 12hr clock?

[@stefaniadellapa8772]

how i can do if it plot on my serial monitor a lot of no sense symbols? (on the example code)

[@hamzacizmecioglu412]

how can ı fix "couldnt find rtc" eror ?

[@adskideanus2862]

If your using Arduino MEGA Try connecting SCL connection to SCL pin ( pin 21 ), and SDA connection to SDA pin ( pin 20) That worked for me :)

[@tiennguyenminh6454]

can i buy this and use 24c32 eeprom only for store memory

[@koldenrjk]

Usiny my windows PC clock - I'm getting wrong time.

Your video is about led matrix esp8266 i took the code from that video but got the error "MD_MAX72xx.h: No such file or dictory" can you tell me how to fix it. Thanks

[@mytectutor]

That is because you have not installed the MD_MAX72xx.h library. Please visit this link for more reference on the libraries necessary for using the LED matrix; mytectutor.com/max7219-led-dot-matrix-display-with-arduino/

[@gokulkrishnan7364]

how much peripherals could we connect parallely for sda&scl pins?????

[@teejay872]

127... that's 7 bits ;-)

[@ludogermain6766]

message d'erreur dans le code 'POSITIVE' was not declared in this scope

[@herediiaa.e]

me too bro

[@herediiaa.e]

did you fix it?

[@srujanendhratalla4187]
