Arduino Analog Read and Tones

Class Recap:

  • Introduction to Arduino
  • Circuits, Symbols and Breadboarding

At the end of class we learned about analog inputs, and how they can be mapped to tone values. Digital inputs work in a similar way, instead of reading various values you will only read 1s and 0s, 5 volts or 0 volts. Arduino programming is very similar to Processing, you can add if statements and for loops; utilize the logic you have learned so far. By adding a conditional statement that listens to the button presses, you can trigger a sound. It could be a piece of music you compose or maybe you can make a piano if you make every button have its own sound.

Assignment:

Create a project that uses the tones function, with your piezo buzzer, you can add either an analog or digital input to trigger the sound. In this prototype you should experiment in making an enclosure. This interface should be conceptual and also interactive, think outside the box, or inside the music box, or an instrument, or a toy 🙂

/////////////////////////////////////////

/*Class Code: This sketch listens to light! Depending on the variable resistance of your photoresistor you can map its value to tones*/

int speaker = 11;
int sensor = A0;
int sensorValue = 0;

void setup() {
Serial.begin(9600);
pinMode(sensor, INPUT);
pinMode(speaker, OUTPUT);
}

void loop() {
sensorValue= analogRead(sensor);
sensorValue = map(sensorValue, 1, 15, 31, 3000);
tone(speaker, sensorValue);
Serial.println(sensorValue);
delay(1000/16);
noTone(speaker);

    But he’s tryiong none the less. I’ve been using WordPress on numerous websites for about
    a year and am concerned aboyt switching to another platform.
    I have heatd very good things about blogengine.net.
    Is there a wayy I can transfer all my wordpress posts into it?
    Any kind of help would be greatly appreciated!

    Hi there would you mind sharing whidh blog platform you’re working with?
    I’m looking to start my own blog in the near future but I’m
    having a hard time choosing betwee BlogEngine/Wordpress/B2evolution and Drupal.
    The reason I ask iss because your layout seems different
    then mosst blogs and I’m looking for something completsly unique.
    P.S Sorry for getting off-topic but I had tto ask!
