💻 Example Arduino Code (Ready to Use)
#include <Adafruit_PWMServoDriver.h>
Adafruit_PWMServoDriver pwm = Adafruit_PWMServoDriver();
#define SERVOMIN 150 // Minimum pulse length
#define SERVOMAX 600 // Maximum pulse length
void setup() {
Serial.begin(9600);
pwm.begin();
pwm.setPWMFreq(50); // Servo frequency (50 Hz)
}
void loop() {
// Move servo on channel 0 from min to max
for (int pulse = SERVOMIN; pulse <= SERVOMAX; pulse++) {
pwm.setPWM(0, 0, pulse);
delay(10);
}
delay(1000);
// Move back from max to min
for (int pulse = SERVOMAX; pulse >= SERVOMIN; pulse—) {
pwm.setPWM(0, 0, pulse);
delay(10);
}
delay(1000);
}
