I’m losing a bit of faith in using a PI as a sprinkler controller. I tried the sprinklers_pi application that was pre-installed on the OSPi SD card, but no matter what I set the GPIO settings to (direct positive or negative) I couldn’t get ANY of the GPIO pins to react at all when I activated a sprinkler. In fact, I set the application to Direct Negative (meaning all the GPIO pins should have been ON when no zones were active), and not a single GPIO pin was active (I tested all with a LED). If anyone has got sprinklers_pi to work, please let me know how, as from what I see thus far, it does nothing.
