Description

This is very simple, cheap and interesting project for the learner. In this LED Binary Clock Circuit, we have used Arduino Nano to control the whole project like reading time from RTC and showing that on LEDs. A 3.0v coin cell is connected to RTC IC for backup. We are showing time here in Binary Values and we can convert that binary time into the decimal values.
