Every now and then while wandering through the wasteland called KZfaq you come across a real gem.. This video is Gold!

Wow, your brain is wired as a clock, I was totally mesmerised listening to you describe how it all works 5 star, thank you so much Bob in the UK

Super extra video. I would like to ask for a video of the readings

thx for the hint to desolder the chargeresistor

Incredible video. So information dense yet easy to understand. I’m trying to make an automated door that will open and close at specific times of the day, set by the user. I’m new to arduino, but I’m having a hard time moving from “hello world” and blinking LEDs to using libraries to control external components over I2C. I bought a ds3231 but man the learning curve is steep. Your video is helping me break through the fog of confusion. Thank you for all the effort you put into making this.

Great video, though please check the BCD conversion at 15:14, it looks like the operations were 'mixed up'

You put a lot of work into this video. Thank you!

I'm truly amazed at how you manage to pack so much information into this video. I spent a long time searching through the datasheet for some of these details before I came across your channel. You're awesome!

Nice tutorial

Great interesting video, well done, understandable 😊 You write at 11:30 inside the video that you want to give an example of setting DS3231 to: 11:23:47 PM October 2023 as well as alarm-1: 11:50:00 pm 28th each month, but without github the code, can I get it from you, you are really good at packaging the code to a minimum, thanks

I like those. Have a couple of Pico's running MMBasic with a DS3231 attached. The temperature "quarters" in register 18 worries me. The integer number in register 17 gives the full number in Celsius directly. Typing RTC getreg 17,a and print a will give 19 (or whatever) degrees and RTC getreg 18,a and print a gives 64 which could mean 0.75 and it's weird to test, but I got to see another number. If it's 64,32,16 then it's still weird. Edit: You answered it to be bit 6 and 7 in the end of the video. The code you showed bit moved (>>) down to 0/1/2/3 as a reading and x 0.25, so I figure it out.

Great video Keep on 🥰🥰

Excellent content.

you saved one person from dying due to library fever😁

Nice, i didnt think there was this much under those clothes, thanks for exposing.
