To drive the LEDs you will have to set the GPIOs as outputs. The LED on the left is a single green
LED whereas the one on the right is a dual green/amber LED. To drive the green LED on the left it
is sufficient to pull the corresponding GPIO 23 high, to turn it bring the GPIO low. For the dual LED
instead you will have to bring GPIO 22 high whilst having GPIO 24 low to turn on the green LED,
with GPIO 22 low and GPIO 24 high you will turn on the amber LED. The animation below
summarises the logic.
