Project Description:
********************

In today’s episode, you will learn how to make a Raspberry Pi Pico based Oscilloscope and logic analyzer powered by an Android Smart phone or Tablet. An oscilloscope is the most essential tool in all of electronics. It is used to graph an electrical signal as it varies over time. Sooner or later you will need an Oscilloscope for Analyzing low or high-frequency PWM signals, you will need it for testing your analog or digital sensors, you will also need an Oscilloscope for testing your timing circuits, wireless devices, function generators, and so on.

The Multimeter and Oscilloscope are two very important measurement tools used extensively for analyzing and diagnosing electrical and electronic circuits, components, devices, etc.

Multimeters are cheap and Oscilloscopes are too expensive and that’s why I decided to make myself the cheapest Oscilloscope on this planet which cost me only 5 dollars. You don’t have to write even a single line of code both the firmware and App are free to download. All you need is to download the Scoppy Oscilloscope firmware from Github, upload it to your Raspberry Pi Pico and you are good to go.

Scoppy App has got lots of buttons; but don’t worry I will explain each and every button and of course I will also explain how to use all these buttons.

After building the Raspberry Pi Pico Oscilloscope then I will share with you test results including,

1. Capacitor charge and discharge testing.

2. Testing an Analog Sensor and

3. We will be measuring the Arduino PWM Signal.

So, without any further delay, let’s get started!!!

Very, very well done vid!
Excellent content. I'll put this together during tomorrow morning's coffee.

As an engineer, I had thousands of hours of scope and logic analyzer use under my belt. Now, 20 years later, I'll purchase a $400 200Mh scope from Amazon, but not for several months.

A few years ago, I watched a similar vid but never followed up in it. I will this time because I actually have serious use for it now.

Thanks for producing this vid. It's very timely for me. You really did a good

[thethoughtfield]

Amazing tutorial, I just loved it. Very detailed. thanks

[evoprox]

Excellent job there, very well done with tons of potential for future projects. Thanks a bunch for the app - I immediately got the paid version and subbed to your channel. Keep it up!

[holzwurm_hd]

Hey. Would it be possible to use the Pi Zero 2W ? And can you put out the signal via Composite?

I am converting Tiny 5 inch CRTs to portable Arcades and thought if it already has a Pi why not include an Oscilloscope application as well?.

0:57 Это было неожиданно) На совершенно случайном видео на английском языке встретить наш советский осцилограф С1-93, за которым несколько лет проработал)

[MisterkeTube]

The limitations of this solution seem to be the very limited voltage range and probably the sample-rate.

[yudhiemekanik]

How about 2 channel?
What pin are used?

[TheJavaSync]

& how to build 2nd ch for premium upgrade version?

[VastCNC]

I wonder if this could be made to work wirelessly with the new pico w.

[katiekumcgil]

sorry for noobiness on this one, what whould the main benifits of using the pico, compared with say a bunch of resisters straight into the headphone socket type of build ?

[pradyumnaguria]

Dear sir, I have failed to firmware pico(made in India). Request to make a long video about firmware

[hishammustafa]

please what is the maximum voltage and frequency this oscilliscope can measure

[techaz.]

Sir please make a video. To test 555 ic multivibrater usin pico pi oscilloscope

[ambalapetlover]

I dont know English very well
Plz tell me what is maximum frequency can i measure using this scope?

[devilssongs]

Can i use arduino board instead of rasp pico ?

[sushantakumar]

What i can use arduino uno on this application scoppy

[vvnnable]

Hi Great Tutorial, can we also check negative signals using this, for example +- 12 v PWM signal, what would be setup on Pico side to measure negative part of the Signal. Thanks

[sweetblues]

I have only arduinodroid coding app how is that?

[robyray]

Hi, I'm not an expert and would like to know if with this oscilloscope is possible measure also the sine wave of the 220 volt elettric current we have at home ....Thanks

[hencosteenberg]

What is the bandwidth of the scope 1MHz or higher?
