A traffic light simulation via 3 LEDs - red, yellow and green.

Wiring

GPIO18 (12) -> Breadboard (+) -> Resistor (220 Ω) -> Red LED long leg (+, anode)
GPIO24 (18) -> Breadboard (+) -> Resistor (220 Ω) -> Yellow LED long leg (+, anode)
GPIO25 (22) -> Breadboard (+) -> Resistor (220 Ω) -> Green LED long leg (+, anode)
GND    (14) -> Breadboard (-) -> LED short leg (-, cathode)

How to run?

Firstly, go to the folder:

cd led

Then run 3led.py:

python 3led.py
