Arduino – Poor Man’s Oscilloscope

234 Flares 234 Flares ×

Hi guys,

Today I’ll talk about a really good project you can do with your Arduino! This is the best way you can have a cheap oscilloscope around, I dind’t wrote this code, I’ve found it on the internet a while back ago and I’ve decided to share this awesome project. Let’s start…2oscopethumb

  • First, download processing. It’s free Click here to download. You don’t need to install anything, It runs like the Arduino IDE.
  • Then Share this page to unlock the Arduino Code and the Processing code …

And then you just need to connect the Arduino analog pin 0 to the signal you want to read.

And It’s done!

This is the Circuit I’ll be measuring , it’s a simple 555 timer circuit… that flashes a LED.

Parts required:

  • 1x Arduino
  • 1x Breadboard
  • 1x LED
  • 1x 10k resistor
  • 1×4.7k resistor
  • 1x 1k resistor
  • 1x 100nF electrolytic capacitor
  • Jumper cables

Schematics:

555 timer

Check my YouTube video and watch it working.

    What is the Scope time base setting?

      actually there’s no windows where you can change the time base, you can do that by changing the code a bit probably
