Stepper motor control using AT89S52 for robotic applications
Stepper motor is found with finds lot applications in computer peripherals, business machines, process control, machine tools and robotics. Especially in robotics and process control like silicon processing, I.C.Bonding and Laser trimming applications, it is necessary to control the stepper motor from remote places. This project is to control the stepper motor using switches. This deals with the design and development of hardware and software for Stepper motor control system. Three switches are used to control the direction of the stepper motor. When the corresponding switches are pressed the stepper motor turns in clockwise, anticlockwise and stop respectively. 16 X 2 Liquid Crystal display (LCD) is provided to display the status of the stepper motor. ULN driver is used to drive the stepper motor. This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.
