Tinsle Town

Description:
In this project I was interested on what sort of sparkly things we could make with the DC motor.  If we put some tinsel on the motor, it creates a cool disco-effect. 
Materials:
 Arduino Uno Board
 DC Motor
Battery Pack
Transistors
 Resistor
 Diode
 Potentiometer
wires (not including extension wires)
Tinsel

int potPin = 0;   // select the input pin for the potentiometer

int motorPin = 9; // select the pin for the Motor

int val = 0;      // variable to store the value coming from the sensor

void setup() {

  Serial.begin(9600);

}

void loop() {

  val = analogRead(potPin);    // read the value from the sensor, between 0 - 1024

  Serial.println(val);

  analogWrite(motorPin, val/4); // analogWrite can be between 0-255
