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.

Today we will look at yet another example in Arduino Basics. It is called ReadAnalogVoltage. You can find this program in the File - Examples - Basics.

If you have ever used a multimeter to check voltage across an electronics circuit, you can think of this experiment as a simulator of the same.
