Creating an Arduino toggle switch can be done using a simple push button. You don't need to buy an actual toggle switch (although it would provide the same operation).When you use a standard push button as an input to a microcontroller pin you can read its state simply by using the ...

T = toggle (write) – just for digital pins This sketch is designed to work with his PHP script, but it could be integrated in other prjects using the syntax above. The PHP script communicate with web interface and Arduino for getting and setting PIN status. If invoked without parameters ...

This function can be used to convert a momentary push button to a toggle switch. By default, the retuen value will toggle true-false then false-true for each onPress action of the button. The setToggleState() function sets the initial state (true or false) The setToggleTrigger() function...
Arduino library for push buttons at INT0 and / or INT1 pin (pin 2 / 3). Provides debouncing and toggle button functionality. - ArminJo/EasyButtonAtInt01
I just figured out, that I need to to configure a button. An after I pushed the button, the display shows something. A second push let the display turn off. Is this behaviour correct? Edit: No correct, you need to activate the Backlight by using the Toggle Switch on the WebGui jeroe...
