PWM Motor Control

PWM Motor Code

This code makes the motor speed up until it reaches the highest speed possible and then it resets to low speed again.

------------------------

int motor = 9;
int speed = 0;

void setup() {
  pinMode(motor, OUTPUT);
}

void loop() {
  analogWrite(motor, speed);

  speed = speed + 31;
  
  if (speed > 250)
  { 
    speed = 255;
  }

  delay(4000);
  
  if (speed > 250)
  { 
    speed = 0;
  }

}

Target Game

Hook up the following circuit starting with the servo first.

int sensorPin = A0;
int ledPin = 13;
int sensorValue;
#include <Servo.h>
Servo myservo;
void setup()
{
  myservo.attach(9);
  pinMode(ledPin, OUTPUT);
  //Serial.begin(9600);
}
void loop()
{
  sensorValue = analogRead(sensorPin);
  //Serial.println(sensorValue); // Print value to monitor
  analogWrite(ledPin, sensorValue);
  if (sensorValue < 100)
  {
  myservo.write(180);              // tell servo to go to position in variable 'pos'
  delay(15);
  }
  else
  {
  myservo.write(90);    
  delay(2000);
  }
}
