Using a Temperature Sensor to Control the Speed of a Motor Using Arduino

Arduino-Temp-Sensor.cpp

float temp; 
int tempPin = A1; //arduino pin used for temperature sensor. CHANGE THIS BASED ON YOUR CONFIGURATION
int tempMin = 70;   
int tempMax = 75;   
int motor = 2;       // the pin where motor is connected. CHANGE THIS BASED ON YOUR CONFIGURATION
int motorSpeed = 0;

void setup() {
 pinMode(motor, OUTPUT);
 pinMode(tempPin, INPUT);
 Serial.begin(9600);
}
void loop() {
  temp = analogRead(tempPin);
  temp = (temp *5.0*100.0)/1024.0; 
  Serial.println(temp);
  delay(1000);     
  if(temp < tempMin) {  
       motorSpeed = 0;      
       digitalWrite(motor, LOW);
   } 
   if((temp >= tempMin) && (temp <= tempMax)) 
   { 
       motorSpeed = map(temp, tempMin, tempMax, 32, 255); 
       analogWrite(motor, motorSpeed);
