Frequency Counter circuit using Arduino in proteus

In this article we will learn how to make Frequency counter circuit using Arduino in proteus.
In the last post we will learn how to Interface Arduino with LCD and Keys simulation in proteus. You can visit our website,
I hope you appreciate my work, let’s discuss about today’s project.
