Sample Arduino Code

When the button on KY-004 is pressed, the following code will turn on the Arduino pin 13 LED.

int led = 13; //Define LED pin
int buttonpin = 3; //Define the button pin
int val; //Define a numeric variable
void setup()
{
pinMode(led,OUTPUT);
pinMode(buttonpin,INPUT);
}
void loop()
{
val = digitalRead(buttonpin); // Check the status of the button
if(val==HIGH) // When the button is pressed, turn on the LED
{
digitalWrite(led,HIGH );
}
else
{
digitalWrite(led,LOW);
}
}
