Using the PIC16F84 Microcontroller in Intelligent Stepper Motor Control

For applications requiring critical rotorpositioning, usually stepper motors are the bestchoice. Stepper motors operate differently fromother motors; rather than voltage being appliedand the rotor spinning smoothly, stepper motorsturn on a series of electrical pulses to the motor'swindings. Each pulse rotates the rotor by an exactdegree and a series of pulses must be generated toperform a complete rotation. An intelligentcontrolling device was conceived and built basedon a PIC16F84 microcontroller and UFDC-1interface.
