Ks0029 keyestudio Digital Push Button

Introduction

This is a basic application module. You can simply plug it into an IO shield to have your first try of Arduino. 
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

Specification

• Supply Voltage: 3.3V to 5V
• Easy to 'plug and operate'
• Large button keypad and high-quality first-class cap
• Achieve interesting and interactive work
• Interface: Digital
• Size: 30*20mm
• Weight: 4g

Connection Diagram

Sample Code

/* # 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
}
