I've built an Arduino LED clock that counts down the days till your expected death.
The flaw at the present moment is when the USB cable is unplugged (or the power goes out,) the clock resets to its hardcoded total days left. Which i no longer valid.
Need help with adding a battery-powered clock component similar to this one: https://www.amazon.ca/gp/product/B07XSZJHHP/ref=ox_sc_saved_title_1?smid=A2VCM95OHZ8CR3&psc=1 so that the days that are left are more accurate and has a way to retain the accurate date after power failure.

Hello, you need ds3231 RTC module to retain the time, i will help you code it hit me on chat so i can start off, i have both Uno and RTC with me
I have 19 years of experience in developing medical products each has battery operated rtc.i can deliver the product as per your requirement and quality. Looking forward to work with you. Thank you.
Hello there, I have read your project detail and have seen all the attachements. I can easily add RTC to your death counter so that it will always save time and never gets reset.
