Project 8: Servo Motor Control

Описание: Project 8: Servo Motor Control

What You'll Build

A servo motor that sweeps back and forth from 0 to 180 degrees automatically.

Circuit Connections

Red wire → 5V
Brown/Black wire → GND
Orange/Yellow wire (signal) → Pin 9

Note: Larger servos may need external power supply
The Code Explained
The code makes the servo sweep smoothly:

Setup:

Attaches the servo to pin 9
Initializes serial communication at 9600 baud


Loop:

Forward sweep (0° to 180°): Increments angle by 1 degree, moves servo, waits 15ms
Pause at 180°: Waits 500ms
Backward sweep (180° to 0°): Decrements angle by 1 degree, moves servo, waits 15ms
Pause at 0°: Waits 500ms
Repeats continuously


Key points of the video

Servo motors provide precise position control (unlike DC motors that just spin)
Standard servos rotate 0-180 degrees
Servo.h library simplifies control
write() sets position in degrees

Components Required:

Arduino Uno R3
SG90 servo motor (or similar)
3 jumper wires
USB cable
Breadboard (optional)

Circuit Connections:

Connect the servo's red wire to 5V for power, brown/black wire to GND for ground, and orange/yellow signal wire to Pin 9 for PWM control. This simple three-wire setup is all you need! Note: Larger servos may require external power supplies.
