Pete posted an article taking a closer look at Maxim’s DS3231 real-time clock: Fortunately, Maxim also offers the DS3231, which is advertised as an “Extremely Accurate I2C-Integrated RTC/TCXO/Crystal”. This chip has the 32kHz crystal integrated into the package itself and uses a built-in temperature sensor to periodically measure the temperature of the crystal and, by […]

Adjusting clock with alarm, hygrometer & thermometer on 1.8″ ST7735 display
Nicu Florica blogged about his adjusting clock with alarm, hygrometer and thermometer on 1.8″ ST7735 display: I use feature from article Another adjusting clock with alarm & thermometer using DS3231 on 1.8″ ST7735 display and change reading internal temperature of DS3231 with DHT22 senzor (AM2302), but you can use a cheaper and not very precise DHT11 […]
Using a $2 DS3231 RTC & AT24C32 EEprom from eBay
From the comments on our ‘Using DS1307 and DS3231 real-time clock modules with Arduino‘ post, Edward Mallon writes: I’ve been putting the $1 DS3231 boards through their paces for quite a while now…and they have been performing well. More details at Edward Mallon’s blog. Via the comments.
Using DS1307 and DS3231 real-time clock modules with Arduino
John Boxall over at Tronixstuff has posted a detailed tutorial on how to on how to use DS1307 and DS3231 real-time clock modules with Arduino: There are two main differences between the ICs on the real-time clock modules, which is the accuracy of the time-keeping. The DS1307 used in the first module works very well, however […]
