DS3231 Arduino Tutorial: Real-Time Clock with LCD1602, Alarms & Temperature
May 4, 2026 - Interface DS3231 RTC with Arduino — set/read time, display on LCD1602 I2C, read temperature, configure Alarm 1, and output a square wave on the SQW pin. Full code included.
People also ask

Can the DS3231 keep time even when Arduino is powered off?
Yes, the DS3231 continues running using its onboard CR2032 battery, so the time remains accurate without external power.

DS3231 Arduino Tutorial: Real-Time Clock with LCD1602, Alarms & ...
What is the I2C address of the DS3231?
The DS3231 uses a fixed I2C address of 0x68. This address is hardwired in the chip and cannot be changed, unlike some other I2C devices that have configurable address pins. If you're placing the DS3231 on the same I2C bus as an LCD1602 (which is typically at 0x27), there is no conflict since the addresses are different.

Why does my DS3231 not trigger the alarm on the SQW pin?
The square-wave output must be disabled using rtc.writeSqwPinMode(DS3231_OFF); otherwise, the pin will not switch to alarm-interrupt mode.

combining the DS3231 & 16x2 LCD display for clock - adafruit industries
December 17, 2018 - Arduino UNO + Adafruit DS3231 which works great and then I added an Adafruit Standard 16x2 LCD ID 181 to give me an accurate 2 line date and time display. I thought I'd add in the Serial Display sketch at the end of the DS3231 but attempting to compile the code gives errors I am not able to fix.

November 26, 2022 - Finding this Arduino Project online for beginners that worked for me was very difficult for me. I tried for about a month and a half and was unsuccessful. I recently came across Visuino and gave it a try. I was amazed. What took me a month and a half and left me without my intended result was eventually accomplished by using Visuino in just a single morning.
