how or where is a example sketch to work off, like to enter f 10 50, to run motor forward at speed 10 for 50 seconds

2

working off this example and got motors working but need serial input to work properly

// connect motor controller pins to Arduino digital pins
// motor one
int enA = 10;
int in1 = 9;
int in2 = 8;
int inByte = 0 ;
void setup()
{
  Serial.begin(9600);
  // set all the motor control pins to outputs
  pinMode(enA, OUTPUT);
 
  pinMode(in1, OUTPUT);
  pinMode(in2, OUTPUT);


}
void demoOne()
{
  // this function will run the motors in both directions at a fixed speed
  // turn on motor A
  digitalWrite(in1, HIGH);
  digitalWrite(in2, LOW);
  // set speed to 200 out of possible range 0~255
  analogWrite(enA, inByte);
  
  delay(2000);
  // now change motor directions
  digitalWrite(in1, LOW);
  digitalWrite(in2, HIGH);  
 
  delay(2000);
  // now turn off motors
  digitalWrite(in1, LOW);
  digitalWrite(in2, LOW);  
  
}

void loop()
{
  if (Serial.available() > 0) {
int inByte = char (Serial.read()) * 100;


  demoOne();
  delay(1000);
 
  }}

no luck with this either

// connect motor controller pins to Arduino digital pins
// motor one
int enA = 10;
int in1 = 9;
int in2 = 8;

int  serIn; //var that will hold the bytes in read from the serialBuffer
void setup()
{
  Serial.begin(9600);
  
  
  // set all the motor control pins to outputs
  pinMode(enA, OUTPUT);
 
  pinMode(in1, OUTPUT);
  pinMode(in2, OUTPUT);


}
void forward()
{
  // this function will run the motors in both directions at a fixed speed
  // turn on motor A
  digitalWrite(in1, HIGH);
  digitalWrite(in2, LOW);
  // set speed to 200 out of possible range 0~255
  analogWrite(enA, 150);
  
  delay(2000);
  // now turn off motors
  digitalWrite(in1, LOW);
  digitalWrite(in2, LOW);
analogWrite(enA, 150);  
}
 void backward()
 {
  // now change motor directions
  digitalWrite(in1, LOW);
  digitalWrite(in2, HIGH);  
 
  delay(2000);
  // now turn off motors
  digitalWrite(in1, LOW);
  digitalWrite(in2, LOW);  
 } 

void loop()
{
 while (Serial.available()>0){
        serIn = Serial.read();	//read Serial  
        
 if (serIn == 'a' ) {
    void forward () ;
  } 
  
   if (serIn == 'b' ) {
    void backward () ;
  } 

  delay(1000);
 
  }}
