One of the few reliable solutions to broadcast a message over the network without concern about the operating system is either using a simple and stupid UDP package (however UDP broadcasts are blocked in many networks) or registering a MDNS service. Basically what you need is some Python code.

There is a strong correlation between torque and current in an Electric motor. For DC motors and servo motors it should be relatively simple to implement but I do not Think there is any simple solution to Control current in an ordinary cheap induction motor. Nicklas Karlsson > Hello! > > I wou
