I will eventually have two pi inputs feeding a single label through separate "blink" functions that blink either "OPENING" or CLOSING" depending on which pi pin is active, for that duration the pin is active. If neither pin is active, the label reads "STOPPED". In the end, each pair of two inject nodes will be replaced by a single pi pin's digital input from a hardware interface so this loop "problem" could not happen on the finished product. I'm just puzzled over it's endless looping after multiple injects of "1". No amount of "0" injects will stop it...
