The aim of this kit touch screen control stepper motor is to use design and construct a user friendly module that can be used that can be used to control the direction and speed of the stepper motor based on touch screen technology. The system consists of the following stages: first the use of touch screen, reading the touch screen press through controller and generating proper output signals. Secondly, it is to receive data from controller for driving the motor properly for proper direction and speed and finally displaying the data on the 16×2 LCD.
This kit touch screen control stepper motor is based on touch screen system which will be divided into section for different inputs as per required for the user. According to section touched the controller check the input and generate the proper output to drive the motors. Since the motors are high current devices this cannot be controlled directly interfaced to the controller. So in order to control proper current, voltage and direction we have used motor driver L293D. The controller check the input and generate the output events as per program (refer the programming file). The outputs through the microcontroller in this project are proper display on LCD of the information. Proper LCD display is ensured through programming and the LCD interface design. Secondly, generate signal to control signals for the motor driver to drive the motors. The motor used here for representation is Nema 17 stepper motor.
