The seconds displayed are chaotic and the minutes go down when the seconds reach 60. But the info displayed on the Lcd is not correct or maybe the reading is wrong.

I am able to set the current time into the RTC.

I have run I2C scan and my DS3231 RTC has the 0x57 address. I have tried many different libraries but problem remains the same : Once you have the RTC up and running, you can experiment with other features such as the alarm feature, and square wave generator… This module can also store some data to EEPROM, but my main reason for upgrading to this module was for the accuracy of the clock itself.I am currently trying to use a DS3231 external RTC on my M5Stack core grey.

I would recommend removing power for a few minutes then powered back up to ensure the CR2032 battery is working, then verify the time again through your serial monitor. Up to this time, I’ve never had to replace a standard CR2032 yet, and I’ve been using the ZS-042 for over six months now. The battery began to bulge and was worthless after just a couple days. I’ve attempted using the standard CR2032 without disabling the charging circuit.

There is a youtube video on how to do this here. This can easily be done by removing the series charging resistor. Wiring: DS3231, BH1750 and BME280: SCL PINS A5 SDA PINS A4 VCC 3. If you are using a standard CR2032 battery, I would strongly recommend disabling the charging circuit. Digital and binary Clock using Arduino, RTC, two LED matrix, operating in 4. Be sure to set your baud rate to 9600 if using this exact code.

This code uses the “Wire” Library.Īfter the upload is complete, you can go to your serial monitor to very the clock is correct. I didn’t want the clock to be reset to this time every time the power is cycled, so then I commented out the “setDS3231time” and uploaded again. This module can be used in 12-hour and 24-hour formats. In this module, the date is set based on whether the month is 29, 30 or 31 days, and also whether it is leap year or not. This RTC module maintains seconds, minutes, hours, day, date, month, and year information. I set the clock about 1 minute ahead of time, and then pressed the upload button about 4 seconds ahead of the time setting because it takes a few seconds for the upload to complete. DS3231 real time clock module features high accuracy and low power consumption. Before uploading, I un-commented the “setDS3231time” line, and adjusted the clock. I found some code on the TronixStuff website to make this module work. Compared to other RTC solutions, this DS3231 module drifts less than a minute per year. The temperature of the crystal is continuously monitored, and the capacitors are adjusted to maintain a stable frequency. The RTC module can be used for applications such as an alarm clock, for time stamping, or simply to display the current time on an LCD display. The DS3231 RTC module integrates DS3231 Real Time Clock (RTC) IC which has an internal crystal and a switched bank of tuning capacitors.

If you have an older Uno, just use A5 for SCL, and A4 for SDA. In my case, I wired VCC to 3.3v on the Uno, GND (ground) to GND, SCL (Serial Clock) to SCL, and SDA (Serial Data) to SDA on the Uno. This module works on I2C (Inter-IC) communication. I only made for connections to make this clock work. The RTC module made of clock chip DS3231.
