When we use the GPIO on Raspberry Pi for experiment,
we will find that there is no pin identifier on it. Thus, we often need to
check the functional properties of GPIO pins, which is inconvenient to extend
the experiment.To make the
experiment easier, this kit will be used, which includes multitudes of
components such as a GPIO T-shaped expansion board, an experimental
board, connecting wires, LED lights, RGB lights, resistors as well as

buttons.
