 \section{Connecting a pushbutton with \arduino\ using a breadboard}

 This section is useful for those who either don't have a shield or don't want to use the shield

 for performing the experiments given in this chapter. 

 

-To know more about the pushbutton, one should watch the Spoken Tutorials on Arduino as published on 

-  {\tt https://spoken-tutorial.org/}. In case, you have a pushbutton and you want to try connecting it with \arduino\ on a breadboard, you should 

-refer to the sixth tutorial titled Arduino with Tricolor LED and Push button on {\tt https://spoken-tutorial.org/}.

-To know the connections, please refer to the figure \ref{fig:ard-pushbtn-bread}. The connections given in this 

-figure can be used to read the status of a pushbutton. 

+To know more about a pushbutton, one should watch the Spoken Tutorials on Arduino as published on 

+  {\tt https://spoken-tutorial.org/}. Ideally, one should go through all the

+tutorials labeled as Basic. However, we strongly recommend the readers should

+watch the fifth and sixth tutorials, i.e., First Arduino Program and 

+Arduino with Tricolor LED and Push button.

+

+In case you have a pushbutton, and you want to connect it with \arduino\ on a breadboard, 

+please refer to \figref{fig:switch-bread}. The connections given in this figure can be used to 

+read the status of a pushbutton. As shown in \figref{fig:switch-bread}, 

+there are three different wires - red, black, and blue. The red wire is used to connect 5V on 

+\arduino\ and one leg of the pushbutton. The black wire connects to one long vertical row on 

+the side of the breadboard to provide access to the ground (GND) on \arduino. 

+The blue wire goes from digital pin 12 to one leg of the pushbutton on another side. 

+That same leg of the pushbutton connects through a pull-down resistor to GND on \arduino. 

+When the pushbutton is open (unpressed), there is no connection between the two legs of the pushbutton, 

+so the pin is connected to the ground (through the pull-down resistor), and we read a LOW. 

+When the button is closed (pressed), it makes a connection between its two legs, 

+connecting the pin to 5V so that we read a HIGH.

 \end{figure}

+The connections shown in \figref{fig:switch-led} can be used to control an RGB LED, 

+depending on the status of the pushbutton. As shown in \figref{fig:switch-led}, digital

+pin 9 on \arduino\ is connected to the rightmost leg of the RGB LED. Rest connections

+are same as that in \figref{fig:switch-bread}.
