This is a basic application module. You can simply plug it into an IO shield to have your first taste of Aduino.
This module is endowed with following advantages:
Wide voltage range from 3.3V to 5V
Standard assembling structure (two 3mm diameter holes with multiple of 5mm as distance from center)
Easily recognizable interfaces of sensors ("A" for analog and "D" for digital)
Icons illustrate sensor function clearly
High quality connector
Immersion gold surface

/* # When you push the digital button, the Led 13 on the board will turn on. Otherwise,the led turns off.
*/
int ledPin = 13; // choose the pin for the LED
int inputPin = 3; // Connect sensor to input pin 3
void setup() {
pinMode(ledPin, OUTPUT); // declare LED as output
pinMode(inputPin, INPUT); // declare pushbutton as input
}
void loop(){
int val = digitalRead(inputPin); // read input value
if (val == HIGH) { // check if the input is HIGH
digitalWrite(ledPin, LOW); // turn LED OFF
} else {
digitalWrite(ledPin, HIGH); // turn LED ON
}
