i've seen than vcc and gnd are always powered on. if i plug only these two cables, the servo Always run. as soon as i plug the signal cable, the servo stops.
should i only use signal, as ground , and +3.3v as vcc ignoring the gnd?
another test i would like to do is putting a very simple nodemcu board in the printed Feeder and let robotank poower It when he need to feed. then the Feeder Will be handled by the nodemcu
