Electronic Control of DC Motors

Graphics displays are gaining popularity in an increasing range of control and user interface applications in markets such as home automation, home appliance, medical and industrial. These kind of displays enhance the user experience and provide detailed information with sharper images. Additionally, graphics displays enable technologies such as touch screen, leading to more effective and efficient interfaces to the applications. In this work, touch screen technology is being employed for controlling the speed and direction of a DC Motor. ATMEGA32 Microcontroller takes the command from the touch screen and the data is transferred to driver circuit (L293D DC Motor Driving IC) and this data is converted to electrical pulses and is fed to the DC Motor. Pulse width modulation technique is employed for controlling the speed and direction of the motor.
