It is an analog world and you need to know how to interface to it. First, identify the voltage and current requirements of the periferals. Electromagnetic elements will need a diode across it to catch the backswing when it is turned off. A suitable power supply and robust MOSFET is usually all that is needed.
Are you going to build it? How will you know if it works?
