Arduino Digital Button with Pullup and Pulldown resistors

click to enlarge Let us learn how a Pushbutton works on an Arduino's board. We will program the Arduino so that It can send a signal to a LED whenever the push button is pressed. We can make the LED turn on with the press of the button, and with some rearrangement of components and the program we can make the LED turn off when the button is pressed.
