Raspberry traffic light by working solution

[Situ LLC]

Good morning. Someone gives me a hand.
I have 3 LEDs to make a traffic light with a Raspberry Pi 3.

If someone has made a small application that can turn on each light when I need it.

I have seen several examples, but it does not show very well the wiring of the LEDs in the electronics of the PI 3B.

I would appreciate your help someone wants to take this small project, give me a price $ Pay by PayPal

Thanks.
