Re: Introduction: Fundamentals of Designing With Microcontrollers

Q:  Are there MCU that can drive a 110V motor directly, or would you interface through solid state relays?

A:  A solid-state relay would be good.  You could also use an MCU to trigger a triac through an opto-isolator.  I have seen some schematic diagrams that use an MCU to directly drive a triac, but in the interest of safety, I'd want an opto-isolator, or opto-coupler between my MCU and line voltage.  Do a Google search for microcontroller triac optocoupler.
