Servo motor SG90
A little motor that turns to a position
In your kit: 1×🔎 What is it?
A servo is a little motor that you can turn to a precise position, from 0 to 180 degrees. For example, you say "go to 90 degrees" and it goes exactly there. You put a little arm on the shaft.
🔌 This is how you connect it
The servo has three wires:
- Orange or yellow (signal) to a pin, for example D9
- Red to 5V
- Brown to GND

✨ What can you do with it?
- A barrier gate
- A pointer that points to the temperature
- A waving robot arm
💡 Tip
Do not turn the arm by hand. Then the little gears inside can break.
