Servo (180°)
Feetech FS90 micro servo, 180° by Feetech ↗
A small motor that turns to an angle you choose, from 0 to 180 degrees.
2Use it
| Pin or leg | What it is for |
|---|---|
| Brown | GND |
| Red | + 5 V |
| Orange | the signal from a pin |
- Brown to GND, red to 5 V, orange to the signal pin.
- 5 V from the Arduino’s 5V pin, or from the USB power board.
- Join its GND to the GND of the board.
- Do not turn the arm by hand: the small gears can break.
Good to know: Give it its own 5 V; a Micro:bit's 3V pin is too weak for it.
