Servo Motor SG90
A precise position-controlled motor. Rotates to specific angles (0-180 degrees). Ideal for robotic arms, steering, and pan-tilt mechanisms.
Overview
A servo motor contains a DC motor, a gear train, and a feedback potentiometer inside a compact package. You send it a PWM signal and it rotates to the corresponding angle. Unlike a DC motor that spins continuously, a standard servo holds its position once it reaches the target angle.
Specifications
| Parameter | Value |
|---|---|
| Operating Voltage | 4.8 - 6V |
| Rotation Range | 180 degrees |
| Torque | 1.8 kg/cm |
Wiring Guide
| Wire Color | Arduino Pin |
|---|---|
| Red | 5V |
| Brown / Black | GND |
| Orange / Yellow | PWM pin (e.g., pin 9) |
For multiple servos, use an external 5V power supply to avoid overloading the Arduino regulator.
Usage in ArduinoStudio
Drag the Servo component onto the canvas, assign a PWM pin, and use the angle action in your sequence to set position (0-180). Chain multiple angle steps to create smooth sweeping motions.
