I wanted to know how I could connect 4 Newton grippers to the controller board on the BlueBoat’s starboard and assign a single servo to control all of them at once. Is it possible to connect their signal wires to one pin (say Pin 9) and be able to activate them? If yes, what should I consider? How the wiring, powering, and servo assignment should be set up? If not, could I perhaps use several PWM pins (say 9 and 10)? Apologies if this was asked already and I missed it.
You can indeed control 4 grippers with a single pin - you would need to splice all 4 yellow signal wires together, and connect them all to battery voltage. Because PWM outputs aren’t typically used on a BlueBoat / ArduRover, you would need to do a bit of setup - this is easier in Cockpit, but possible in QGC as well.
I’m very curious to learn about your goals for such a setup!
