Arduino Merry-Go-Round Code
#include <Servo.h>
Servo merryGoRound;
void setup() {
merryGoRound.attach(9);
}
void loop() {
for(int pos = 0; pos <= 180; pos++) {
merryGoRound.write(pos);
delay(15);
}
for(int pos = 180; pos >= 0; pos--) {
merryGoRound.write(pos);
delay(15);
}
}Code Explanation
Including Servo Library
#include <Servo.h>This library helps control servo motors easily.
Creating Servo Object
Servo merryGoRound;Creates a servo motor object.
Attaching Servo
merryGoRound.attach(9);Connects the servo motor to digital pin 9.
Rotating Forward
for(int pos = 0; pos <= 180; pos++)Moves the motor from 0° to 180°.
Rotating Backward
for(int pos = 180; pos >= 0; pos--)Returns the motor back to its original position.
Project Output
After uploading the code:
- The motor starts rotating automatically.
- The merry-go-round platform begins moving.
- Continuous movement simulates a fair ride.
- Students can observe motor control in action.
