Lab03 Rotating piano and forte

Posted by

Description

For the normal lab requirement, I had one rotating control for brightness and one rotating control for blinking rate. I mapped these controls using soldered potentiometers.

For extra credit, I  wanted to improve upon my previous piano/forte Lab 2. I mapped one pot to a variable called dynamic, which when rotated would switch from ‘p’ mode to ‘mp mode’ to ‘f’ mode. The other pot mapped to the blinking rate.

Materials

  • Jumper cables
  • Potentiometers (2)
  • Ping pong ball diffuser
  • Cotton
  • Arduino
  • 3 LED’s
  • Breadboard

    • Code (Lab Requirement)


    int sensorPin = A0;
    int sensorPin2 = A1; // select the input pin for the potentiometer
    int ledPin = 11; // select the pin for the LED
    int ledPin2 = 10;
    int ledPin3 = 9;
    int sensorValue = 0; // variable to store the value coming from the sensor
    int sensorValue2 = 0;

    void setup() {
    // declare the ledPin as an OUTPUT:
    pinMode(sensorPin, INPUT);
    pinMode(sensorPin2, INPUT);
    pinMode(ledPin, OUTPUT);
    pinMode(ledPin2, OUTPUT);
    pinMode(ledPin3, OUTPUT);
    Serial.begin(9600);
    }

    void loop() {
    // read the value from the sensor:

    sensorValue = analogRead(sensorPin);
    sensorValue2 = analogRead(sensorPin2);
    Serial.print(sensorValue);
    Serial.print(",");
    Serial.print(sensorValue2);
    Serial.println("");
    // turn the ledPin on
    analogWrite(ledPin, (sensorValue2 / 4));
    analogWrite(ledPin2, (sensorValue2 / 4));
    analogWrite(ledPin3, (sensorValue2 / 4));
    // stop the program for milliseconds:
    delay(sensorValue);
    analogWrite(ledPin, 0);
    analogWrite(ledPin2, 0);
    analogWrite(ledPin3, 0);
    // stop the program for milliseconds:
    delay(sensorValue);

    This is what happens when dynamic is set to the highest and wait is set to almost the lowest. The color crescendo is really fast.
