Have you ever wondered if you can turn your smartphone into a digital oscilloscope? In this short yet informative video, we’ll show you exactly how to do that using just a few simple tools and a free mobile app. Whether you're an electronics student, a DIY enthusiast, or someone working with Arduino, Raspberry Pi, or other microcontrollers, this trick will save you time and money.

Traditional oscilloscopes can be expensive and bulky—but with this method, all you need is a smartphone, an audio jack or USB OTG connection, and the right app to start visualizing signals like PWM (Pulse Width Modulation), analog inputs, and even waveform patterns from your circuits. This is especially useful when you're on the go, working on prototyping, or just want a quick way to debug your hardware without needing a full lab setup.

We’ll guide you through how to connect your Arduino (or similar device) to your phone, set up the app, and view signal behavior in real-time. This is a creative and cost-effective solution for hobbyists and learners exploring signal analysis, electronics fundamentals, and embedded systems.
