Octopus Button Switch Brick

From Wiki

Introduction

By using Octopus electronic bricks, you may connect Arduino/Freaduino compatible boards easily with various digital, analog and I2C/Uart interfaces. These the breadboard-less firm connection are prepared to extensive modules like poteniometers, sensors, relays, servos…even buttons, just plug and play.

This is a a Button Switch with Circle Transparent Cap , which detects your press action. It is ideal for beginner class to test the Arduino or be your first sensor in your project. It was easy be used for Chipkit, STM32, AVR, ARM and others mirc-MCU.

The Freaduino Sensor Shield is the perfect shield to connect this senor to Arduino. Or Freaduino UNO which we had pre-stray Octopus Brick interface.

Programming

Includes important code snippet. Demo code like :

int ledPin = 13;                // choose the pin for the LED
int inputPin = 14;               // Connect sensor to input pin 3 
 
 
void setup() {
  pinMode(ledPin, OUTPUT);      // declare LED as output
  pinMode(inputPin, INPUT);     // declare pushbutton as input
}
 
void loop(){
  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
  }
}
