Top 5 Arduino Oscilloscope Projects with Code

An Arduino Oscilloscope is a budget-friendly, educational project that converts a standard Arduino board into a basic digital storage oscilloscope (DSO) to visualize electrical waveforms. While it cannot replace an expensive professional benchtop oscilloscope, it serves as an excellent low-cost tool for beginners, hobbyists, and students looking to understand circuit debugging and signal behavior. How It Works Under the Hood

An Arduino oscilloscope relies entirely on the microcontroller’s built-in peripheral hardware to sample and translate live inputs: A simple DIY Oscilloscope with Arduino Uno and Mega
