Arduino Based Real-Time Clock With Temperature Display

This project demonstrates how you can build a real-time clock (RTC) with a temperature display using Arduino, DS3231 RTC chip, and SSD1306 OLED display (128×64 pixel). DS3231 RTC chip is more accurate than DS1307 and also has a built-in temperature sensor. It keeps the time running even when the main power source is down. It […]
