Stepper motors in students' projects - when and how to use them

Developments in simplifying the programming of PIC Microcontrollers have made the devices more accessible to students and to school technology departments. Following our paper on interfacing with the PIC, our research I has shown that although many Key Stage 3 and 4 students are now beginning to use PICs in their design and make projects, for many students driving LEDs to simulate output devices is still as far as they wish to get. Our research also shows that recently in many schools much progress appears to have been made and DC motors and other inductive devices are being interfaced with the PIC and both Key Stages 3 and 4. We have been asked to take the initial paper a little bit forward and produce some guidelines for driving stepper motors. This paper provides a short background on the functionality of stepper motors and goes on to describe some possible ways of driving st
