The project aims to develop a high precision linear actuator for some special applications like syringe infusion pump, auto focused microscope, micro fluidics etc. The tailored model is intended to test the torque capacity of a specific stepper motor along with the performance of the control circuit. The electronic circuit includes a microcontroller (ATmega328P) which is programmed to generate the pulses for the motor driver unit of the control circuit. The stepper motor driver unit consists of ULN2003A IC to provide sufficient current in order to excite the individual inductive coil inside the stepper. In this stage, we adopted the half stepping algorithm for this unipolar stepper motor to provide maximum torque during the operation.
