This repository contains code and resources for interfacing an Arduino with a Real-Time Clock (RTC) module and an I2C LCD display. The RTC module keeps track of the current time and date even when the ...

Now Let's Make a DIY Arduino Digital Clock using DS3231 and LCD. Material Required: Arduino Uno; DS3231 RTC Module; LCD Display 16*2; Jumper Wire; 10K Preset; 3V coin cell (CR2032) Arduino Digital ...

We have previously used DS3231 RTC with Arduino in below projects: Automatic Pet Feeder using Arduino; ... They are the lcd.h file for working with LCD display, the PIC16F877a_I2C.h file for working ...

Fig. 2 shows the circuit diagram of the automatic school bell. It is built around Arduino Uno R3, 16×2 LCD display with I2C (MOD1), DS3231 RTC, 4×4 matrix keypad, 5V SPDT relay, 230V AC call bell, and ...

It uses the I2C interface to communicate with the master device (microcontroller), in this case the Arduino. DS3231 and SSD1306 OLED share the same I2C bus, but the microcontroller can communicate ...

Reference circuit diagram of an Arduino-compatible LCD backpack is shown below. What follows next is information on how to use one of these inexpensive backpacks to interface with a microcontroller in ...

Macetech’s ChronoDot is a Real Time Clock module for projects requiring highly accurate time keeping and measurement. The ChronoDot uses the DS3231 chip, which features a TCXO to compensate f… ...
