Arduino Frequency Counter Code Explanation: Code for this frequency measurement using arduino is quite simple and easily understandable.Here we are explaining the pulseIn function which is mainly ...

So [Todd] has set out to build an Arduino frequency counter for a Kenwood TS-520S HF ham radio. This post (and the video found after the break) doesn’t cover the entire project.

Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. The whole circuit can ...

I use that in a lot of Circuit VR posts so you can click on a circuit and see it live. However, the simulator does not save the source code in the virtual Arduino. You have to do that yourself.
