Introduction to hardware
- Okay, before we get started with controlling the physical world with the Raspberry PI, lets talk a little bit about the hardware. In our situation, we're using the Raspberry PI Zero, and just like all Raspberry PIs, there are a series of GPIO pins here, a general-purpose input/output. There are power, 3.3 volts, five volts, different ways of communicating, but we're really talking about power. We need five volts eventually for our project. And then, we're also going to be talking about GPIO pins, which allow us to turn them on or off in the specific sequence or a specific amount of time when we're controlling a servo. So, just like the full-size board, we have the header pins, and this is the one we'll be working with. This has the header pin soldered on, but I thought for this case, we'll talk about it without the header pin, so we can get a good view of it. And, check online for the way these are laid out. They…
