TKButton

Module

Description

With the constructor TKButton you can create a software object for each button module connected to the TinkerKit Sensor Shield and assign it the physical input pin on which is connected. For example if you have a button connected to the input pin I0, you might write:

TKButton button(I0);

Available methods

*get()*	return the button reading. HIGH if is pressed, LOW if is released
*pressed()*	trigger the instant when the button is being pressed and return the HIGH value
*released()*	trigger the instant when the button is being released and return the HIGH value
*held()*	this method compares the state of the button with the previous one and return HIGH if is held
*toggle()*	with this method the button acts like a switch. Each press change the return value, that can be HIGH or LOW

Example

/*
Button

Turns on and off a T010111 LED Module connected to O0,
when pressing a T000180 pushbutton attached to I0.

// include the TinkerKit library
#include <TinkerKit.h>

TKButton button(I0); // creating the object 'button' that belongs to the 'TKButton' class
// and giving the value to the desired input pin

TKLed led(O0); // creating the object 'led' that belongs to the 'TKLed' class
// and giving the value to the desired output pin

void setup() {
// TinkerKit 'object' eliminate the need for pin declaration with pinMode()
}

void loop()
{
// check if the pushbutton is pressed

if (button.get() == HIGH) { // if it is, the button.state() is HIGH
led.on(); // turn LED on
}
else { // if it is not, the button.state() is LOW
led.off(); // turn LED off
}
}
