In a nutshell main difference between the two is: We are going to compare between stopwatch and countdown timer in this section. How to decrement digits on 7 segment display using IC4026Ī countdown timer is a digital or an analogue or a software timer which counts the time in backwards to show the amount of time left, a countdown timer stops counting when the counts reaches zero.In this post we are going to construct a proper real time countdown timer circuit using 7 segment display and Arduino.
