Linker butten is the button,the module has two versions, There are two buttons, the big one is a single button, another is the double button.Take the single button as an example.

linker butten on the circuit, is the most simple input device, but also the most used input device, In this example, the button is used to control LED lights bright and dark.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”1/1″][vc_tour][vc_tab title=”Hardware required” tab_id=”1392718710-1-81″][vc_column_text]The components used in this experiment are shown below:

The components are one LED light, five Male to Female Dupont Line, one linker butten,  and one pcduino.
