Assignment: DC Motor: Actuation Assignment 1

Collaborators:

This ghostie greets visitors who 'stand on the welcome mat' with a happy little dance, but touch the ghostie and he gets rather angry!

When the force sensor is triggered by a visitor, the motor, with offset weight, creates a gentle swing, but when one of the force sensors is occluded, the vibration becomes strong. The next feature I want to add is sound: when happy, the ghost sings, but when angry, makes a warning scream!

Code:

int photoPin1 = 0;   // select the input pin for the first photocell

int photoPin2 = 1;   // select the input pin for the second photocell

int forcePin = 2 ;

int ledPin2 = 11;

int ledPin1 = 10;

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

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

int photoVal1 = 0;

int photoVal2 = 0;

void setup() {

  Serial.begin(9600);

}

void loop() {

  forceVal = analogRead(forcePin);

  photoVal1 = analogRead(photoPin1);

  photoVal2 = analogRead(photoPin2);

  Serial.println(forcePin);

  Serial.println(photoVal2);

  Serial.println(photoVal1);

  if(forceVal > 0 ){

    //do something happy

    analogWrite(motorPin, 25); //spin gently

  }else if(photoVal1 < 100 || photoVal2 < 100){

    //do something angry

    analogWrite(motorPin, 200); //vibrate wildly!

  }

}
