Simple and inexpensive microcomputer-controllable stepping motor and drive circuit.
The construction of a simple stepper motor and drive circuit made from commercial components is described. The use of the stepper motor for a monochromator wavelength drive is discussed. The rate and direction of scan can be controlled by either a hardwired timer circuit or by a microcomputer.
