So [Todd] has set out to build an Arduino frequency counter for a ... add external component to facilitate this. That extra circuit design will be the topic of the next project segment.

Of course, one could almost accomplish this by just using an Arduino Due ... explaining the design and his experiments. Even though this isn’t quite a cut-and-paste circuit solution at ...

Want to build a complex circuit-based project with your ... If you want to design precise components for your Arduino setups, ...
