Timothy Vance’s Soft Switch

Code:

/*
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.

// constants won’t change. They’re used here to
// set pin numbers:
const int buttonPin = 2; // the number of the pushbutton pin
const int ledPin = 13; // the number of the LED pin
const int ledPin2 = 12;
// Pin 13: Arduino has an LED connected on pin 13
// Pin 11: Teensy 2.0 has the LED on pin 11
// Pin 6: Teensy++ 2.0 has the LED on pin 6
// Pin 13: Teensy 3.0 has the LED on pin 13

// variables will change:
int buttonState = 0; // variable for reading the pushbutton status

void setup() {
// initialize the LED pin as an output:
pinMode(ledPin, OUTPUT);
// initialize the pushbutton pin as an input:
pinMode(buttonPin, INPUT);
}

void loop(){
// read the state of the pushbutton value:
buttonState = digitalRead(buttonPin);

// check if the pushbutton is pressed.
// if it is, the buttonState is HIGH:
if (buttonState == HIGH) {
// turn LED on:
digitalWrite(ledPin, HIGH);
digitalWrite(ledPin2, LOW);
}
else {
// turn LED off:
digitalWrite(ledPin, LOW);
digitalWrite(ledPin2, HIGH);
}
}

Structure

My soft switch works off of a small cardboard structure that works similarly to that of a plug when the pieces are apart the light on the left is on.

When the two cardboard pieces are together the light of the right activates.
