Oscilloscopes are expensive and largely reserved for makers or electronics engineers O who need to understand what a circuit is doing. We can’t make our own, simple oscilloscope and logic analyser with a £4 Raspberry Pi Pico, right? It turns out that with a Raspberry Pi Pico, some software called Scoppy and an old Android phone, we can do just that.
For the low, low price, we can’t expect the earth. This won’t rival an expensive setup, but for most of us, it is enough to understand and get to grips with the equipment before we open up our wallet.
In this tutorial, we learn how to configure a Raspberry Pi Pico as an oscilloscope and use the Android app to read live data from a circuit. Note that due to the Raspberry Pi Pico’s 3.3V logic, we cannot measure voltages any higher, otherwise we risk
