Step Generator Using the 4093 (MEC160E)

This circuit is part of my book Robotics, Mechatronics and Artificial Intelligence (sold out) published in the United States. It can be used as a control shield for stepper motors in mechatronics or robotics projects or as a building block for simple projects. A step generator is shown in Figure 1. This circuit uses a CMOS IC and can drive translators of the same logic type.

It is also an oscillator that produces the necessary pulses at a frequency that determines the speed of the stepper motor. When S1 is closed, C1 is put in the circuit, stepping down the frequency and the speed of the motor. P1 adjusts the speed range of the motor.
