How To Make Digital Clock Using Sun Board version 2

Hello friends, this is my new project. This is a 24 hours digital clock using arduino and DS3231 module. I used 20×4 I2C lcd module to show big font of digit and also used sun board to make a good looking box. Its very simple to make. Just follow all the step and make your own clock.

Components:

Sun board
Arduino nano : https://amzn.to/3tPRBB9
20×4 LCD Display :https://amzn.to/2RVZIPx
DS3231 Module : https://amzn.to/3ePcRTb
Push Button
TP-4056 Module https://amzn.to/2S2kugs
MT-3608 Module https://amzn.to/3u0lwqB
