Bottom line, it is definitely fun to build and play with, it also makes a cool EMF detector

I donРІР‚в„ўt have a professional function generator so I could only test its range from 100 ms to about 1 ms scales.

Another unfortunate feature is that the analog input only shows positive voltage so the scope is really a positive DC or AC scope only. Here again custom electronics could be built but there is something beautiful about keeping it simple.

The setup is really simple, connect an Arduino Pro Mini to a Nokia 3310 LCD screen, sample an analog port and then wright the pixels to the screen. I even added two potentiometers, one that adds delay to the sample to essentially provide a basic time scale and another pot that can scale down voltages as long as they are below three volts (the operating voltage of the micro controller). Unfortunately if you want to sample sign waves that have voltages over three volts you are out of luck unless you build an electronic circuit to scale it down somehow.

I donРІР‚в„ўt claim that this device can replace actual test equipment but it might be useful and for $40.00 bucks in total parts it is a blast to play with.

IРІР‚в„ўve seen videos on YouTube using an Arduino and a Graphical LCD screen (GLCD) to create a simple Oscilloscope. The annoying thing is that I found no help whatsoever on how to build one. I spent a few days figuring out how to use the Nokia 3310 LCD screen and then figuring out how to sample an analog port to create a fun oscilloscope effect.
