Real Time Clock Kit
with Arduino_DS3231RTC_SSD1306 OLED
Overview
This tutorial shows how to build a real time clock and timing alarm clock
using Arduino DS3231RTC and SSD1306 OLED. The DS3231RTC is used as
a real time clock chip which keeps the time running even if the main
power supply is off (with the help of a battery), time, date and
temperature of nano board are displayed on the SSD1306 OLED.
This digital clock mainly uses the arduino nano board to read the time of
the DS3231 clock module, and then controls the OLED display the real
time. When the time reaches the set reminder time, the buzzer will
automatically sound. The clock can also monitor the real-time
temperature of the system, and the time can be adjusted manually.
