Added a propeller and motor to my toy plane! Very simple but tons of fun. Very simple.

Materials

• -cardboard plane (cardboard, hot glue, wooden stick, duct tape)
• -motor
• -Balsa wood propeller
• -Arduino uno
• -transistor
• -2 AA batteries and holder
• -1 10k potentiometer 

Code (from lab :):

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
}
