Introduction to and wiring up a single servo
- Okay. Now let's talk about servos or adding motion to our Raspberry Pi. And servos are essentially DC geared motors but they have some limits in them. I'll show you here. I can go from that far to that far, usually about a 180 degree swing. There's also different sizes of servos. This is a micro servo. There's continuous rotation servos There's much more powerful servos, but basically it's a DC geared motor that can sweep about 180 degrees and there's a potentiometer in there so it gives feedback on where it is. So it's really nice as I can tell it to go specifically to ten degrees or forty five degrees or ninety degrees and it knows where it is and it stays there. It's really cool. Now the best practices for servos is to have a separate power supply. And that is because this requires five volts. The Raspberry Pi has five volts, but this can draw some extra power that the Raspberry Pi can't provide. Now…
