Further dissection of the pooh bear, using a DC motor to imitate the girl from the Exorcist. (Pooh's head spins around while still attached to his body)

Components Used 

  • Arduino Board
  • Bread board
  • 1 1K ohm resistor
  • 1 transistor (TIP 120)
  • 1 Diode
  • 1 DC Motor 
  • wiring
  • 1 pooh bear 

    Arduino Code 

    /* * one pot fades one motor * modified version of AnalogInput * by DojoDave <> *  * Modified again by dave */int potPin = 0;   // select the input pin for the potentiometerint motorPin = 9; // select the pin for the Motorint val = 0;      // variable to store the value coming from the sensorvoid 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}

    Nice work, and suitably spooky... It's a good starting point for the Halloween Party this week! Now that you have a Pooh bear with a spinning head, I'm curious about what you're going to do with it. What type of interaction is it part of? E.g. is it designed to scare people? To be part of some larger process? Etc...?
