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 didn’t write 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…
First, download processing. It’s free Click here to download. You don’t need to install anything, It runs like the Arduino IDE.
Upload this code to your Arduino
Then Run this code in Processing IDE
And then you just need to connect the Arduino analog pin 0 to the signal you want to read.
And It’s done!
- 1x Arduino (Click to see on Amazon)
- 1x Breadboard
- 1x LED
- 1x 10k resistor
- 1×4.7k resistor
- 1x 1k resistor
- 1x 100nF electrolytic capacitor
- Jumper cables
This is the circuit I’ll be measuring , it’s a simple 555 timer circuit… that flashes an LED.
