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

Step 3: Arduino Code
Download the DS3231 library and import it in your arduino software.
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.
