Configuring GPIO outputs
By clicking on the arrows highlighted with the red circle above, the GPIOs will change from inputs to outputs as
shown in the image below. Once the GPIO is an output, the block next to the output arrow will turn yellow and
display "0" indicating that the default output state will be low upon power-up. Clicking on the this block will
change it to a "1" indicating that the default output state will be high upon power-up. An example of this is
shown below for GPIO2.
