A simple DIY Oscilloscope with Arduino Uno and Mega
My DIY Oscilloscope, how i got my signal
– Credits and links
I am experimenting with RF and IR signals in various frequencies and had some trouble with the receivers and needed to see what kind of signal i was receiving.
I cannot afford a real oscilloscope but i knew about the older Arduino oscilloscopes.
After trying many different versions of code and tutorials, I was unable to get a single one to work, and all the tutorials and guides around was 2-3 years old.
Not sure if it is the IDE or the actual hardware that has changed in such a way that it didn’t work anymore.
I finally found a working oscilloscope from a Japanese website, (linked below) and a working TFT screen library,
meaning i could read the various signals received.
Clearly the limitations are 0-5v but that is fine, what i needed to know is either wave type and frequency, and this is sufficient.
It also gives me an indication of the amplitude which is just a nice bonus.
But what I’m most happy with, is the two channel feature, i often use the second channel as a reference point to be able to
differentiate the main channel on the screen.
