PushButtons (Circuit 07)

/*
  Button
 
 Turns on and off a light emitting diode(LED) connected to digital  
 pin 13, when pressing a pushbutton attached to pin 2. 
 
 
 The circuit:
 * LED attached from pin 13 to ground 
 * pushbutton attached to pin 2 from +5V
 * 10K resistor attached to pin 2 from ground
 
 * Note: on most Arduinos there is already an LED on the board
 attached to pin 13.

Unfortunately, I took no video. Use your imagination.

int ledPin = 13; // choose the pin for the LED 
int inputPin1 = 3; // button 1 
int inputPin2 = 2; // button 2 
  
void setup() { 
  pinMode(ledPin, OUTPUT); // declare LED as output

    digitalWrite(ledPin, LOW); // turn LED OFF 
  } else if (digitalRead(inputPin2) == LOW) { 
    digitalWrite(ledPin, HIGH); // turn LED ON

Proximity Sensor experiment

Rather than wiring up the given diagrams for sensors from the book, I made a circuit using something I hadn’t used before. I made a simple circuit which plays tones based on a value measured from a proximity sensor.

Here is the video:

Here is the fritzing diagram:

Here is the code:

/* 
 * Proximity instrument
 * This is totally not anything like a theramin.
 * Author: Matthew Kellogg

 */
int ledPin = 5;    // LED connected to digital pin 9

void setup()  { 
  pinMode(ledPin, OUTPUT);
  Serial.begin(9600);
} 

static const int thresh = 160;

void loop()  {
  int val = analogRead(0);
  if (val > thresh){
    analogWrite(ledPin, map(val, 30, 950, 0, 255));
    tone(11, map(val, thresh, 950, 60, 4400));
  } else { 
    analogWrite(ledPin, 0);
    noTone(11);
  }

PushButton.

IRL:

In Fritzing:

In Action:

My Code:

const int buttonPin1 = 2;     
const int buttonPin2 = 3;
const int ledPin =  9;      

int buttonState1 = 0;     
int buttonState2 = 0;

void setup() {
  pinMode(ledPin, OUTPUT);      
  pinMode(buttonPin1, INPUT);     
  pinMode(buttonPin2, INPUT);
}

void loop(){
  buttonState1 = digitalRead(buttonPin1);
  buttonState2 = digitalRead(buttonPin2);
  int value = 0;
  if (buttonState1 == HIGH) {  
      Serial.println("1");    
      value += 100;
  } 
  if (buttonState2 == HIGH) {
      Serial.println("2");
      value += 100; 
  }
  analogWrite(ledPin, value);
  delay(15);
}
