A powerful feature of the raspberry pi is the row of gpio general purpose input output pins along the top edge of the board.
Gpio header pins.
These are the big numbers e g.
The gpio is the most basic yet accessible aspect of the raspberry pi.
Gpio pins are digital which means they can have two states off or on.
