Introduction: Temperature Alarm and Time on a LCD Screen With a DS3231, Buzzer And LED

About: Arduino Projects :)

In this article we will measure the temperature and the RTC clock time with the DS3231 module.

We will implement a buzzer and led for the temperature alarm.

After that, we will display these values on a A000096 1.17 inch TFT/LCD screen!

Read the tutorial below or the youtube video! :)

Download the Arduino Sketch from below & upload it to your Arduino.

Step 4: Result

The temperature value & time value is are displayed on the LCD screen.

In the Arduino code you can adjust the parameters for the min and max limit for the temperature alarm.
