Erin and Charissa: Catduino

For this week's experiment, we made a cat! Nothing groundbreaking or particularly new here, just trying to make something fun with the few sensors/actuators we have. Turn the dial to make the cat turn, and pet  the photo resistor on its head to make it glow brighter!

The code is after the break....





Turning Cat Code:

// Based on

// File > Examples > Servo > Knob

// Controlling a servo position using a 

// potentiometer (variable resistor)

// by Michal Rinott //

//also based on Fade, Analog Input (David Cuartielles, modified by Tom Igoe), and AnalogInOutSerial (Tom Igoe)

                // control a servo

                // connect the

                // potentiometer

int val;     // variable to read the 

             //value from the analog pin

int lightPin = A2;    // select the input pin for the potentiometer

int ledPin = 11;      // select the pin for the LED

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

int outputValue = 0;  //value output to the PWM (analog out)

   // declare the ledPin as an OUTPUT:

  pinMode(ledPin, OUTPUT);  

  Serial.begin(9600);

  myservo.attach(9);// attaches the servo

    // servo on pin 9 to the servo object

    pinMode(0, INPUT); //analog pin 0 is an input

  

}

    

void loop()

{

  val = analogRead(sensorPin);// reads the value

               // of the potentiometer

               //(value between 0 and 900)

  val = map(val, 0, 1023, 0, 179);

      // scale it to use it with the servo

      // (value between 0 and 180)

                      // according to the 

                      // scaled value

                      // to get there

 // read the value from the sensor:

outputValue = map(sensorValue, 60, 700, 0, 255);  

  // turn the ledPin on

  analogWrite(ledPin, outputValue);  

  // stop the program for <sensorValue> milliseconds:
