Section 8.2 LED with a push button

Now that we understand breadboards a bit, we’re now going to manually blink the LED using a push button placed onto the breadboard and have it act like a switch. Therefore, when the button is pressed, the LED will turn on and when the button is released the LED will turn off. The button just acts like a wire so you can plug in the button anywhere in the circuit.
