Sample Arduino Code
CopyEdit#include <Servo.h> Servo myServo; void setup() { myServo.attach(9); myServo.write(90); // Set to center position } void loop() { myServo.write(0); // Move to 0° delay(1000); myServo.write(180); // Move to 180° delay(1000); }
This code uses the built-in Servo library. It sweeps the servo from 0 to 180 degrees.
Applications
Arduino-controlled pan/tilt systems
Small robotic arms and legs
RC airplanes, cars, and boats
Animatronics and motion control setups
Precise angular movement in compact builds
