This tutorial introduces you to the basic techniques used to run small DC, DC servo,
stepper, and R/C servo motors with microcontrollers. It concentrates on using the microcontrollers
made by the Microchip Corporation, with particular emphasis on the 16F877A
and 18F4331 40-pin microcontrollers. It uses microEngineering Labs’ LAB-X1 board to
make things easier for the experimenter, but you do not need to have the board to learn
to do what needs to be done. Other MCUs and microprocessors made by other manufacturers
can also be used. They are similar, and techniques similar to those developed
herein are used. (Running larger motors is essentially a matter of using more
