Ziyi’s switch

IMG_3904.jpg

Here is my circuit. When the white line from the positive pole touch the fabric, the LED light on. I have two lines from the negative pole to connect two LED lights.

Here is the video that show how my switch works.

This is the code I used, and I need make sure that buttonPin is 2 and my connection need also be 2, ledPin is 13 and my connection must be 13.

const int buttonPin = 2; // the number of the pushbutton pin
const int ledPin = 13; // the number of the LED pin

// 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);
} else {
// turn LED off:
digitalWrite(ledPin, LOW);
}
}
