Arduino oscilloscope for automotive sensor diagnostic

[brajomobil]

It is finally here. It took me almost 3 months to learn, arduino, processing... (never programmed anything...)
Another 3 months to compare data with real oscilloscope...

If you have any questions... I'm here....

Wow, many, many thanks brajomobil for posting this. I had been waiting for this since you mentioned a while back that you'd be working on this project.

Interesting.
This is a single-channel 'scope, though?
It might be better to get 2 channels, even if it means dropping the sample-rate quite a bit.

You can log all arduino analog pins. (6 channels) .But sampling rate drops quite a bit
It is not a problem for slow sensors. e.g. ABS . For fast signal arduino UNO is capable
only for one channel. I am running some tests with arduino DUE and probably will manage
to get usable oFFscope dual channel. Just need to find time...

I wish I could understand the practical side of electronics like you guys.I retired just as the electronic era took over.

I know how to use a slide rule !!

Wow, very impressive. Thanks for posting

Ron; it's never too late to start...

I recommend the Parallax WAM (What's A Microcontroller) kit and book as a good intorduction.
The book can be downloaded on their site, so no need to spend cash, yet.

And if anything is unclear, they have the best forum around.

Note, their Basic Stamp II that is used in the book may be a mite expensive, compared to an Arduino, which is true. And that is really why those pesky Italians made the first Arduinos, too.
(Both operate on 5V, though, so a circuit design used in the book can easily be adapted for the Arduino)

I think RS-components have most Parallax products in their inventory.
