semaphore pic12f629

[Leonardo]

Hello,
Someone can guide me to do a semaphore using a pic12f629 with which one can vary the speed of lighting of the LEDs.

Thanks for any suggestions

What do you want to control the speed with? A pot or have a set of pre determined speeds selected by button pushes or some other manner?

Hello,

Determined speeds selected by button pushes.

Thanks

First we need to work on the schematic. The way it is drawn the red and green leds will never light up. Yellow is OK.

You will also want it rigged so if a green is on the corresponding red at the other fixture will be off.

Take a look here and see if you want to use a configuration something like the drawing with three pins (with a little tweaking)
