The board also contains six buttons and LEDs, located on the
front side. Buttons
(1)
can be used to apply the desired logic
state to pins of the MCU they are routed to. Pressing any of the
six buttons can change the logic state of the microcontroller
pins from logic high (1) to logic low (0).

LEDs
(2)
can be used to visually indicate a logic state of the
specific pin. The maximum current through a single LED is
limited with the 4.7k resistor. Each LED is connected to a
MCU pin, and an active LED indicates that a logic high (1) is
present.
