How to use Arduino Real Time Clock module with DS1302 chip

- In this video, I'm going through the basics of how you can connect and interface a Real-Time Clock (RTC) module based on the DS1302 IC with Arduino.
A Real-Time Clock, or RTC for short, is an integrated circuit that keeps track of time. It uses a backup battery to maintain time in the event that the main power source is removed.
Additionally, I go over the principle of operation of this chip and why it is required in certain types of projects where time tracking is vital.
The code used in this example can be found in the Instructable for the project:
www.instructables.com/Real-Ti...
The library used in the example is Rtc By Makuna

👍nice useful tutorial. Please create more projects with rtc module. 👌
Thanks! Will do definitely!
Great information and nice work. New subscriber
Thanks and welcome 👍👍👍
this one help me creat a real time clock module using RTC thank you
👍👍👍
This is very well explained, thank you. But I am wondering - you said the battery is being (trickle)charged (0:45). The battery you are using is not rechargeable. Could that be a problem?
These batteries are all based on lithium so I guess some small current does not harm them. So far I haven't had a problem at all.
Hello Bill .....im from South Africa and my sons do online racing I am interested in developing a gearshift device which they can use as a gear shifter on either side of their steering wheels. They currently use ordinary switches but the more complex wheels use Hall Sensors. How can i get more in touch with you to possibly help me to change the switches out for Hall sensors .......
Hey Robert, I don't usually do personal help on projects but my I would suggest that you mount a magnet on the lever of the shifter and then, behind it you can mount the hall effect sensor. You will need one that detects presence of a magnetic field and not the ones that work as on/off switches (detect magnetic polarity). Feel free to contact me through my Facebook page.
Thanks a lot
You are welcomed!
I hve problem. I first upload the code using cable. Then i unplug it and using battery 9v to it. Btw mine use arduino uno. It doesnt updatind new time. Example i run on 9.00 (10/6/2023) and when i unplug and connect the battery at 10.00 the same day it just show the 9.00am one not the updating
I had that once happening to me as well but with a low-voltage battery on the module. I replaced it with a new battery and it never happened again.
@@TasteTheCode okay i wil try use new battery. THANKSSSS
At 10:03, in the serial monitor, a load of junk appears on line 3. What and why is that?
It happens when the reset button is pressed on the NodeMCU but I'm not really sure why. You can see it happening at 11:02 I guess it has to do with the processor starting up and maybe using different baud rate at start. I've seen this with many microcontrollers but I've never really paid any attention to it.
@@TasteTheCode Thank you, I am learning, your reply is appreciated.
You are welcome!
Hi, is there a way to get the day of the week?
There is a function on the library called DayOfWeek() that returns 0-6, where 0 is Sunday, 1 is Monday, etc.
@@TasteTheCode Thank you. I have been viewing your channel recently. It is very interesting.
Thank you! I'm glad that you like it!
Is there a way to use a battery instead of cable to power source?
Yes you can. You will either need to provide 5V on the Vin pin or 3.3V regulated on any of the 3V3 pins. I have another project where I'm using power bank ICs to make a project power supply for this purpose. You can check it here: th-cam.com/video/Ze9JscCxLx8/w-d-xo.html
@@TasteTheCode Thank you, i'm doing this for a school project and they gave me an arduino board and a 9V Battery Snap DC Cable. However, I found your video and ordered the DS1302 and the NodeMCU and I just wanted to ask, does the 9V battery snap work with the NodeMCU?
Arduinos, work on 5V, and the Uno especially have a mich larger voltage regulator to handle higher voltage range. NodeMCU works on 3.3V, and I think the max you can provide on the Vin pin is 5V. However, if tou have the Arduino, the same code should work on it as it works on the NodeMCU so you can basically just swap them.
@@TasteTheCode Could you please send me a link or the name of a battery and/or battery holder that would work on this. Sorry I am completely new to this and I am struggling.
@@Filo-qn8pj I'm not sure what you need. Arduino Uno will work on a 9V battery and you can still use the RTC module on it in exactly the same way as on the NodeMCU.
Tambahan program untuk lcdnya bagaimana ya bg?
Check my other videos. I already published one for the LCD.
Apakah RTC 1302 bisa terhubung dengan esp 32 cam untuk penjadwalan pengambilan photo dan dikirimkan ke telegram jika bisa menggunakan pin yang mana mohon bantuannya
Yes it can but that is not something that is simply executed.
ci sono siti che danno data ora e minuti
Yes, but this is handy if the project is not connected on the internet.
@@TasteTheCode sure but since it has a wi-fi module I thought...
I often use NodeMCUs as just demonstration, basically using them instead of an Arduino Nano or Uno.
Complete gibberish!
😱😱😱
I tried this with my ds 1302. It returns
19/80/2091 44:127:1 +
RTC lost confidence in the DateTime!
data read (20) = "⸮G
Do you know why this happens?
Did you set the time initially? Check that the battery is OK and that it is making a good connection. I had a bad battery making weird issues once.
@@TasteTheCode The compiled time is set. The battery has 3 Volts and I think it has a good connection. I also tried changing the battery. That didn't work either. Could my ds 1302 be broken?
I've never seen one to fail but it's not impossible. Do you have another one to try?
