A controller is a device which takes one or more inputs and adjusts its outputs so a connected device functions in a controlled manner. There exist a wide range of controllers from simple motor controllers to advanced microcontrollers that can be tasked with multiple control outputs and perform closed-loop control. Different actuators require differing control methods to achieve stable output, choosing an appropriate controller is therefore important to the final operation of your project.
Cables, Wires & Connectors are the parts you need to be able to connect your electric components to each other.
