Connection Diagram
As we can see in the diagram, we connect the button to the 10K ohm resistor on the negative side as well as to the
GPIO port at GPIO17. The other pin of the button goes to 3V pin on the raspberry pi.
Please note: if you connect the button on the wrong direction the raspberry pi might indicate the opposite, GPIO
HIGH when the button is released and GPIO LOW when the button is pressed, therefore the script might not work as
expected.
