Now let’s write a very basic Arduino program which turns on the LED when we press the push button switch and turns OFF the LED as we release the pressure applied on the Push Button. There are some types of the Sensors which gives you ground or 0 as the output signal and the other types of the Sensors give you 1 or 5v as the output signal. You know we have two types of the Sensors. Why I have not connected 5 volts with the Push Button? One more thing that I would like to talk about, I am sure you might be thinking about, why I have connected ground with the Push Button switch? An LED is connected with pin number 13 of the Arduino through a 330 ohm resistor. The same connections will also work with the Mega. As you can see one side of the Push Button is connected with the ground while the other side of the Push Button Switch is connected with the Arduino’s pin number 2. As you can see for now I am not using any Pull Up resistor with the Push Button. This is the basic and simplest connection diagram that I can start with. For the best explanation I am going to use the Proteus simulation software. Now let’s start with the very basic connection diagram and Arduino program. The push button switch that I am going to use in this tutorial is of the type normally open. The momentary switches can be subdivided into normally open and normally close types. The Momentary switches work only as long as you press on them. These Push Buttons are also known as the Momentary contact switches. When you release the pressure, the spring retracts and the contact is interrupted due to which the current flow immediately stops. Inside a Push Button there is a small spring which makes contact with two wires, allowing electricity to flow when you press it.
A Push Button is used to complete an electric circuit when you press on it.

Push buttons are most commonly used in Calculators, cell phones, TV remote controllers, kitchen appliances, industrial machines, keypads etc.Ī Push Button is made up of hard material usually plastic or metal. Using a digital multimeter you can easily find which legs are internally connected.
Some Push Buttons have 2 legs, some have 3 legs, and some have 4 legs or even more. The working principle of all the Push buttons is exactly the same. Push Buttons are available in different shapes, sizes, and colors. I would appreciate your support in this way!Ī Push Button which is also spelled Pushbutton is a simple switch mechanism which is used for controlling a process it can be a small LED or a big machine. I may make a commission if you buy the components through these links. Without any further delay, let’s get started!!!

How to use the Arduino’s Internal Pull Up resistor?.Why we use a resistor with the Push Button?.
Using a Push Button is very simple in the beginning but as you dig further the things become a little complicated because there are things that you need to take care of which I will explain in a minute. Every beginner love to learn, how to control an LED using a Push Button. No doubt when we first start learning any microcontroller, the very first electronic component that we are introduced to is the LED, and of course, the second component is the Push-button. As this tutorial is for beginners, so, I will try to cover the extreme basics.
