run a motor using arduino
int motorPin = 9;
void setup() {
pinMode(motorPin, OUTPUT);
Serial.begin(9600);
while (! Serial);
Serial.println("Speed 0 to 255");
}
void loop() {
if (Serial.available()) {
int speed = Serial.parseInt();
if (speed >= 0 && speed <= 255) {
analogWrite(motorPin, speed);
}
}
}

int motorPin = 3;
void setup() {
}
void loop() {
digitalWrite(motorPin, HIGH);
}
Thank you!

const int pwm = 2 ; //initializing pin 2 as pwm
const int in_1 = 8 ;
const int in_2 = 9 ;
//For providing logic to L298 IC to choose the direction of the DC motor
void setup() {
pinMode(pwm,OUTPUT) ; //we have to set PWM pin as output
pinMode(in_1,OUTPUT) ; //Logic pins are also set as output
pinMode(in_2,OUTPUT) ;
}
void loop() {
//For Clock wise motion , in_1 = High , in_2 = Low
digitalWrite(in_1,HIGH) ;
digitalWrite(in_2,LOW) ;
analogWrite(pwm,255) ;
/* setting pwm of the motor to 255 we can change the speed of rotation
by changing pwm input but we are only using arduino so we are using highest
value to driver the motor */
//Clockwise for 3 secs
delay(3000) ;
//For brake
digitalWrite(in_1,HIGH) ;
digitalWrite(in_2,HIGH) ;
delay(1000) ;
//For Anti Clock-wise motion - IN_1 = LOW , IN_2 = HIGH
digitalWrite(in_1,LOW) ;
digitalWrite(in_2,HIGH) ;
delay(3000) ;
//For brake
digitalWrite(in_1,HIGH) ;
digitalWrite(in_2,HIGH) ;
delay(1000) ;
}
Thank you!
