Hi am Aniket patil. i would like to get details on touch screen based wireless dc motor speed and direction control using rf ppt.Now i am living at Kolhapur.and i last sudied in D.Y.Patil technical campus Talsande.

Abstract: Now a days, touch screen based home appliance and digital electronic equipment control becomes
one of the major research issues. Basically, touch screen allows the equipments to be controlled so easily than
that of the manual switching system. Considering the ongoing demands of this technology in electrical and
electronic equipment, this research aims at providing a concise idea and design of touch screen based
technology to control the speed of the DC MOTOR using the programmable system on chip (PSOC) microcontroller.
In this research, we have used resistive touch screen based technology because of its widespread
acceptance and as a tool to rescue a person from the danger of electric shock with conventional switches. The
purpose of this research is also to provide a framework for Programmable Touch screen based DC Motor speed
control. The methodology we adopted was based on grouping of micro-controller with touch screen. In
controlling the speed of the motor, varying average voltage was sent to the motor by switching the motor
supply on and off very quickly using Pulse Width Modulation (PWM) technique. Our proposed system
contributes in more accurate speed control, is safer, reduce unwanted power loss, Finally improves the
switching efficiency.

I. Introduction
Now a days, touch screen based home appliance and digital electronic equipment control becomes one
of the major research issues. Basically, touch screen allows the equipments to be controlled so easily than that of
the manual switching system. A user are now able to process their instructions to a machine with a easy or
multi-touch gestures. Research shows that, the touch screen gives better operator mobility when producing
similar manipulation performance. All of the above discussed opportunity motivate us to incorporate Fourwire
resistive touch screen technology (i.e., to find out both the X and Y coordinates, It uses upper and lower
layers of the touchscreen "sandwich" in controlling the DC motor‟s speed with the use of PIC16F876A
micro-controller to provide the user with a easy touch in using the motors. To control motor speed some
research has been done by the researcher, but their research is far different from the model we have proposed
and implemented. Krunal patel et al. proposed a system to control the heavy load crane with the use of touch
screen. They have done so with use of HMI (Human Machine Interface) and PLC (Programmable Logic
Controller) on Drive and AC motor and got better control.
M.Pragna et al. developed a touch screen based system to control the accelerometer based motor
speed and direction of robot using arduino. They have applied the PWD technique along with two
microcontroller and achieve a measurable performance. An idea to incorporate touch screen to control the speed
of the single phase induction motor was provided by Sarat Kumar Sahoo et. al. where they have used PSOC
microcontroller to reduce space consumption and ensure easinessof design.Their work assume remote control to
control speed of the AC motor. But, with the use of the our proposed model, user could easily control the speed
of the motor to get desired output as the system we proposed is programmable. Also, our proposed system aim
at more accurate speed control, is safer, reduce unwanted power loss, improve the switching efficiency, finally
improve the system accuracy.
The following sections are organized as follows: proposed architecture, implementation requirements,
Intemented Circuit diagram, programming of Micro- Controller and finally result and conclusion section.
II. System Architecture
As stated earliar, the purpose of this paper is to control the speed of the DC motor using touch screen.
To do so, we have divided our proposed model into two parts such as controller option and RPM section as in
Fig. 1. We use resistive touch screen as input device and fed the input to the microcontroller. The output of
microcontroller is then fed to Driver to amplify the motor speed and send to the RPM section. To measure motor
RPM we have used optical encoder and then we have amplified output using two amplifier. We have then use
the TTL converter to remove the DC offset voltage.
