Arduino 16 channel PWM Servo Motor Shield

Arduino 16 Channel PWM Servo Motor Shield Documentation

Overview

The Arduino 16 Channel PWM Servo Motor Shield is a convenient and powerful tool for controlling multiple servo motors using an Arduino board. This shield allows you to connect up to 16 servo motors and control them independently, making it ideal for robotics, animatronics, and other applications that require precision motor control.

Features

Controls up to 16 servo motors
 On-board power switch for servo motors
 Supply voltage: 5V or 6V (via external power source)
 Compatible with most Arduino boards

Pinouts

The shield has two rows of headers, one for connecting to the Arduino board and another for connecting servo motors.

Arduino Header:
	+ VCC: 5V power from Arduino
	+ GND: Ground from Arduino
	+ SCL: I2C clock signal
	+ SDA: I2C data signal
 Servo Header (16 channels):
	+ VCC: 5V power for servo motors
	+ GND: Ground for servo motors
	+ SIG: PWM signal for each servo motor

Code Examples

### Example 1: Basic Servo Control

This example demonstrates how to control a single servo motor using the shield. Replace `<servo_channel>` with the desired servo channel number (0-15).
```c++
#include <Servo.h>

Servo myServo; // create a Servo object

void setup() {
  myServo.attach(<servo_channel>); // attach the servo to the specified channel
}

void loop() {
  myServo.write(0); // set the servo to 0 degrees
  delay(1000);
  myServo.write(90); // set the servo to 90 degrees
  delay(1000);
  myServo.write(180); // set the servo to 180 degrees
  delay(1000);
}
```
### Example 2: Multiple Servo Control with Animation

This example demonstrates how to control multiple servo motors and create a simple animation using the shield. Replace `<servo_channel1>`, `<servo_channel2>`, and `<servo_channel3>` with the desired servo channel numbers (0-15).
```c++
#include <Servo.h>

Servo servo1, servo2, servo3; // create Servo objects for each channel

void setup() {
  servo1.attach(<servo_channel1>);
  servo2.attach(<servo_channel2>);
  servo3.attach(<servo_channel3>);
}

void loop() {
  // animation sequence
  for (int i = 0; i <= 180; i++) {
    servo1.write(i);
    servo2.write(180 - i);
    servo3.write(i);
    delay(20);
  }
  for (int i = 180; i >= 0; i--) {
    servo1.write(i);
    servo2.write(180 - i);
    servo3.write(i);
    delay(20);
  }
}
```
### Example 3: I2C Communication with Multiple Shields

This example demonstrates how to control multiple Arduino 16 Channel PWM Servo Motor Shields using I2C communication. Replace `<shield_address1>`, `<shield_address2>`, and `<shield_address3>` with the desired I2C addresses for each shield (0x20-0x27).
```c++
#include <Wire.h>
#include <Servo.h>

Servo servo1, servo2, servo3; // create Servo objects for each channel
const int shieldAddress1 = <shield_address1>;
const int shieldAddress2 = <shield_address2>;
const int shieldAddress3 = <shield_address3>;

void setup() {
  Wire.begin();
  servo1.attach(0); // attach servo to channel 0 on shield 1
  servo2.attach(0); // attach servo to channel 0 on shield 2
  servo3.attach(0); // attach servo to channel 0 on shield 3
}

void loop() {
  // control servos on each shield
  Wire.beginTransmission(shieldAddress1);
  servo1.write(90);
  Wire.endTransmission();
  
  Wire.beginTransmission(shieldAddress2);
  servo2.write(45);
  Wire.endTransmission();
  
  Wire.beginTransmission(shieldAddress3);
  servo3.write(135);
  Wire.endTransmission();
  delay(1000);
}
```
Note: In this example, you need to set the I2C address of each shield using jumpers or soldering, according to the shield's documentation.
