GPIO is one of the most powerful features of the Raspberry Pi — but it can also feel confusing if you’re new to it.
In this video, I introduce the basics of GPIO (General Purpose Input/Output) and show how you can use it to control and read real-world electronics using a Raspberry Pi.
We’ll cover:
What GPIO actually is
What it means for a pin to be “on” or “off”
Driving a 3.3V LED directly from a GPIO pin
Driving a 5V LED safely using a transistor
Reading the state of a GPIO pin as an input
This video focuses on understanding what’s happening electrically as well as how to wire things up correctly — no prior electronics experience required.
If you’ve ever wanted to move beyond software and start interacting with real hardware using your Raspberry Pi, this is the perfect place to start.
