This paper lays emphasis on thedevelopment of low cost controllers for stepper motors in contrast to its resource limitations such as memory size, few I/O pins and computing power compared to High-end designs. The microchip AVR ATtiny45 microcontroller was employed alongside a redesigned (reduced-input pin count) pulse distribution circuit for two H-Bridge drivers. The motor can rotate in both directions as well as possible speed control. The concept of the motor control signals was modeled in Matlab/Simulink, firmware was written in Atmel AVRStudio development environment, while theoverall design was carried out in Proteus software followed by Hardware implementation. Total material cost is about $5 which would be less in commercial production cases.
