All of my technically unchallenged friends have or have access or have used an Oscilliscope, i have seen them, but i have never used one myself.
I wish to test my duino circuits & have a better understanding of what is truly happening under the hood.
I will mainly be using it with my Arduino's & wonder for the price if the following would suffice? http://www.ebay.com.au/itm/ARM-DSO-Nano-Pocket-Sized-Portable-Digital-Oscilloscope-/170663256339?hash=item27bc52a113
Can anyone provide some useful links, tutorials or books please?
no, but a scope is dead simple to use once you figure out what you want to do
on the screen left to right is time, up and down is voltage
as I told our intern, the magic of using a scope is figuring out which way to turn the knob (or the picture of the knob in your case)
set your voltage scale to what you intend to see, maybe a bit higher, dial in your time scale until you can get good measurements, play with it a couple days and you will be able to dial it in like a radio station.
MJLorton is a good guy. He posts over on eevblog a lot.
The first post has a LONG video (basically a recorded class) on oscilloscopes:
There are multiple good videos in this thread. Basically, watch the first one and then follow up with some of the others and you will be more adept at oscilloscopes that almost all the people on these sites.
