How to build your own super simple oscilloscope [tutorial]

I was playing with my radar in my room in Colombia.

But the radar library I created had some problems.

The code worked perfectly when it was not in “Arduino library” form.

…but when I modified it into a library, it just didn’t work at all.

So I needed an oscilloscope to debug.

Just to check if there was actually any action on the UART lines.

I did some research and found a cool and simple way to turn my Arduino into an oscilloscope.

And here’s how to do it:

This is perfect if you need an oscilloscope right now, but all you have is an Arduino.

Keep on Soldering!
