B4J Question Raspberry traffic light wire connection

[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.

I would appreciate your advance help I have information that you can give me

thanks .

It would appear that this is a breakout board which connects directly to the raspberry Pi. Have a look at this link. The connections are GPIO 9,10 and 11 directly on the GPIO header of the Pi. There is also a code example in Python would should be easy to convert to B4J.

Have fun.

or in B4J:

except it uses different pins, but that might just be a case of changing:

pinRed.Initialize(27, False)
pinYellow.Initialize(28, False)
pinGreen.Initialize(29, False)

to use pins:

Red = IO9 = pin 21
Yellow = IO10 = pin 19
Green = IO11 = pin 23
