When the capacitor gets charged the voltage on pin 2 will be high, so the output will be GND (it
is a Push-Pull output), the blue LED will turn OFF and the red LED will light up, because it is
already connected to 5V through 220Ω resistor, it is in need only to GND to light up, and pin 7
will be 0V so the capacitor will discharge.
When the capacitor gets almost empty, the voltage on pin 2 will be low, so the blue LED will light
up and the red LED will turn OFF, and the capacitor will recharge because the voltage on pin 7
is almost 5V, and so on.
