RTC Clock Bangla Tutorial | Easily Make Real-Time Clock with Arduino and DS3231 RTC Module

Easily Make Real-Time Clock with Arduino and DS3231 RTC Module | RTC Clock Bangla Tutorial

📌JLCPCB $2 for 5 pcs 2layer pcb prototype/ 4 layer pcb prototype : https://jlcpcb.com

The PCB board will be needed to make the trainer board like the picture above. According to the above circuit, you can build a trainer on the Vero board. I made my PCB board from http://www.jlcpcb.com. Gerber file is required to order on this website. If you want to get the Gerber file of this PCB, enter this link https://youtu.be/tpIZDV5NqpI. And if you want to design a PCB yourself, then go. at http://easyeda.com.

In this blog, I am going to share with you How to make an RTC Digital Clock using Atmega328p IC or Arduino Uno Board.

The Major Topics Covered in This Video: ------------------------------------------------------------------ 🔥 How do I make an Arduino digital clock? 🔥 How do you make a digital clock? 🔥 What is the Arduino clock? 🔥 Does Arduino have a built-in clock?
