Pushbuttons or switches connect two points in a circuit when you press them. When the pushbutton is open (unpressed) there is no connection between the two legs of the pushbutton. Because the internal pull-up on pin 2 is active and connected to 5V, we read HIGH when the button is op...
Next we will declare three int varaibles to hold the x value, y value and the push button state. Initially, they are set to 0. int Horizontal_Position = 0; int y_Position = 0; int button_State = 0; Inside the setup() function we will first open the serial communication at a baud...

and translates the high resolution digital output of the touch controller into an analog signal within the expected ranges of the original joystick. [Matteo] says he still has to implement the stick’s digital push button, but thanks to an impressive 63 levels of pressure sensitivity on the pad...
Next, you create a variable to hold the button state. By default, it’s 0 (not pressed). intbuttonState=0; In thesetup(), you initialize the button as anINPUT, and the LED as anOUTPUT. For that, you use thepinMode()function that accepts the pin you are referring to, and the mo...

This article shows how you can use a simple, ultra low current pushbutton, an LED and a few I/O lines to implement pushbutton power switch for an Arduino. Simply press the pushbutton for a few seconds and the Arduino will power on and run code. Then, push and hold the pushbutton un...
