Touch screen based controlling of wireless DC Motor

Description

The aim of this wireless control DC motor is to use design and construct a user-friendly module that can be used to control the direction and speed of the DC motor based on touch screen technology. There is wireless control that is the motor end is at the remote location. The wireless technique used here is RF communication. The project consists of the following stages: first the use of touch screen, reading the touch screen press through the controller and generating proper output signals which will be transmitted over RF channel. The transmitted data is received by the RF receiver and fed to the controller which then on its basis generates a signal for driving the motor properly for proper direction and speed and finally displays the data on the 16x2 LCD.

This wireless control DC motor kit is based on touch screen system which will be divided into section for different inputs as per required for the user. According to the section touched the controller checks the input and generates a signal that is wirelessly transmitted to a remote RF receiver. The receiver gives the signal to the controller and the controller generates the proper output to drive the motors and display the data on LCD.

Since the Wireless Control 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 checks the input and generates the output events as per the program (refer to the programming file). The outputs through the microcontroller in this project are properly displayed on the LCD of the information (receiver). The proper LCD display is ensured through programming and the LCD interface design. Secondly, generate signals to control signals for the motor driver to drive the motors. The motor used here for representation is DC geared motor. At transmitter generate a proper signal to be transmitted.
