How to display 3 temperature numbers on seven segment?

[arindambala]

Sir, thank you so much for this great video. Sir, please add a custom time adjustment function with push button or rotary encoder with this module.

Please advise - your clock works OK but will not update the time of the DS3231 when I do an upload. have tried 2 x DS3231 boards with the same results, also tried 3 x Arduino Nano boards. Is the time picked up from the laptop time - it woild seem so. Would this be a library problem? Where can I get the include file for the DS3231 that you used in your original clock? Otherwise very easy sketch to follow - great software! Last thought is for "ZERO" suppression? I love your videos!

Pls provide RTC library link used in your videos . i cant find the suitable library yet.

[bobinnes]

Further to my comment 25th Mar. please advise where to get the exact libraries for DS3231 and TM1637 that you used for the clock, as there are lots of them hanging around, so I cannot compile your sketch, there is something still missing in the libraries I am using.

I make this clock .clock working fine.wher are connect two push button and pot another points ?

[kiranshashiny]

Let's say the button cell runs out and we have to put a new one - then don't we have to set the time on the DS3231 for the first time as the RTC may not know what is the current date/time. First timer question.

Hi! I wanted to do a circuit like this, I managed to do one with a watch, but when I saw what you did I bought another display. I changed the code and now it shows only the date; my problem is that the RTC module resets when the power is turned off, so I have to adjust the date from the buttons. Do you think you can help me ? Adding 2 push buttons. Thank you.

hello bro how about if I Change the existing 7 Segment with large 7 segement example 2.3 inch 7 segment with 7Volt?? can i colaborate it with tm1637? Thank You.

What code do I need to input to have the temp read in fahrenheit.
