Oscilloscopes come in all different shapes and sizes, and now with just a few discreet components, maker Peter Balch has been able to turn an Arduino Nano into an oscilloscope the size of a matchbox. 

The simplest version of this device, which he calls the “ArdOsc,” displays data on a computer screen, but a 1.3” OLED can also be added if you want to use it on its own.

His build write-up goes through several versions of the instrument, progressively adding capabilities including a logic display, signal generator, and other useful tools. It’s certainly worth checking out, whether you need tiny test equipment or just want to marvel at how something this small can be made!

This oscilloscope costs the price of an Arduino Nano, plus a few pence for resistors, etc. Its specifications are:

  • Max 1M samples/second, min 1000sps
  • 8-bits per sample
  • DC 0-5V; AC +/- 550mV, AC +/- 117mV, AC +/- 25mV
  • USB “PC scope” or built-in display
  • Could be battery-powered
  • Optional logic display
  • Optional frequency meter
  • Optional voltmeter

Oscillo-02

Starting a new project is always a fun yet effective way to hone your skills while exploring circuitry and programming. To help improve his engineering chops, Joop Brokking recently bought an inexpensive oscilloscope (a device for visualizing voltage over time in an x-y graph) and connected it to an Arduino Uno. He then shared his findings in a detailed tutorial on YouTube.

In the video below, Brokking is using a Hantek 6022BE 20MHz dual-channel oscilloscope and provides three examples to better understand what can go wrong when building a simple Arduino setup.

A simple DIY Oscilloscope with Arduino Uno and Mega

by vaupell:

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.

Oscillo2-500x349

by prem_ranjan @ open-electronics.org:

We have designed an Oscilloscope using PC and Arduino Board. The signal is first of all fed to the Arduino Board where the analog signal is converted to a digital signal by the ADC which is then serially outputted to the PC and is read by the MATLAB software via the COM ports. Here the signal is read in the form of digital data but then is converted to analog one by using the resolution of the ADC used by the Arduino Board. The MATLAB software was then used to plot the signals.

This instructable will show you how to build a portable Touch Screen Oscilloscope for less than 40 U$! johnag @ instructables.com writes:

The oscilloscope is one of the most powerful electronic instruments that is available to electronics hobbyist, experimenters, and engineers. It is mainly used to measue time-varying signals. Any time you have a signal that varies with time( slowly, quickly, and /or periodically ) you can use an oscilloscope to measure it , visualize it, and to find any unexpected features in it.

Arduino oscilloscope at five megasamples per second

arduino hacks, oscilloscope, tool hacks Commenti disabilitati su Arduino oscilloscope at five megasamples per second 

arduino-5-megasamples-oscilloscoper

There’s no substitute for a proper oscilloscope on your electronics bench. But unfortunately we still don’t have one of our own. But we’ve got an Arduino board and paired with another IC it can sample an astonishing 5 million cycles per second.

[Bob Davis] has been working on an Arduino based oscillscope for a while now. He keep squeezing more and more performance out of it. A previous version hit 3 megasamples using an AD775 chip. When he added a FIFO buffer chip he was able to squeeze 10-25 megasamples out of it… wow! Unfortunately the output tended to be glitchy.

This version gets rid of the AD775 in favor of a CA3306. Both are analog-to-digital converters but the new circuit is less complex and more reliable. It uses just three capacitors and an external clock to support the IC. Take a look at the video below to see how it performs. He’s outputting a graph of the samples on a small LCD screen. The best part is that since the extra chip is doing the sampling this can be ported to your microcontroller of choice.

It has been 7 years (!) since I posted my PIC18F2550 KS0108 Graphical LCD Oscilloscope code and schematics. I have long since taken the circuit apart, sold my PIC microcontrollers, and moved on in my life (as one can surmise from my most recent posts detailing my graduate and postdoctoral work). However, I still get inquiries about the Microchip PIC oscilloscope, so I decided to recreate it using a simpler setup using my Arduino Fio.
