In this tutorial will learn how to do a Timer or Stop watch based on the arduino UNO and DS1307 Real Time Clock RTC.
This is Part 2, we will convert the RTC data from integers to strings in order to simulate the strings data that you may find it in the excel sheet or online. Then, we convert them back to integers, process them to calculate the elapsed time, and at the end we will convert them back to strings for display.
