The aim of this system is to show how position of the dc motor can be controlled by using PID algorithm in LabVIEW for camera movement. Arduino microcontroller board is used to control the DC motor. L298N dual H Bridge motor driver is used to drive the DC motor and to execute the pulse width modulation PWM signal. Proportional Integral Derivative PID is the most common control algorithm used in industrial applications and other control system. DC motor will be interfaced with LabVIEW using an Arduino Uno microcontroller. The position of the DC motor will be set by creating a Graphic User Interface GUI in LabVIEW. LabVIEW GUI sends serial command to the microcontroller for driving PWM pins of the DC motor . DC motor will move by the user in LabVIEW for position control. The output is sent back to the PID controller in Uno microcontroller. PID compares the actual position of the DC motor with the desired position. In this system, PID controller is used to reduce the error and rotate the motor to the set point value for the camera movement control.

Abstract In any industry speed control of an electric drive system is very critical and crucial. Every designer aims at achieving a control methodology having high degree of precision. But industry needs are ever evolving in nature. Hence it is very much essential that along with conventional speed control mechanisms we must also have simple interactive graphical based control strategies. Several algorithms/methodologies have been developed over the years to achieve speed control of motors. In this context by encompassing the usability of Mat Lab, work has been done to control the speed of stepper motor and DC motor using microcontroller. Microcontroller is programmed to achieve bi directional speed control. The main objective of this work is to develop the graphical user interface of motor control through mat Lab guide and the interface of the same with hardware via serial communication.

FOUR QUADRANT SPEED CONTROL OF DC MOTOR USING AT89S52 MICROCONTROLLERJournal For Research

Speed control of a machine is the most vital and important part in any industrial organization. This paper is designed to develop a four quadrant speed control system for a DC motor using microcontroller. The motor is operated in four quadrants i.e. clockwise, counter clock-wise, forward brake and reverse brake. It also has a feature of speed control. The four quadrant operation of the dc motor is best suited for industries where motors are used and as per requirement they can rotate in clockwise, counter-clockwise and also apply brakes immediately in both the directions. In case of a specific operation in industrial environment, the motor needs to be stopped immediately. In such scenario, this proposed system is very apt as forward brake and reverse brake are its integral features. Instantaneous brake in both the directions happens as a result of applying a reverse voltage across the running motor for a brief period and the speed control of the motor can be achieved with the PWM pulses generated by the microcontroller. The microcontroller used in this project is from 8051 family. Push buttons are provided for the operation of the motor which are interfaced to the microcontroller that provides an input signal to it and controls the speed of the motor through a motor driver IC. The speed and direction of DC motor has been observed on digital CRO. Microcontroller programming has been written in assembly language by using notepad and it has been converted in hex file by using micro vision Kiel. The burning of programming in the 8051 microcontroller chip has been done by using positron boot loader software.

Happy May and Happy Weekend, My Guest Students.
Weekends seem more popular for Workshop Class Days lol.
These Presentations are timeless. Tune in anytime, any weekend.
<<I am Adult EDU Vocational, Ordained, Certified and Experienced. Course genres are personal development for holistic health, healing, and self care. I am also skilled in Health Sciences. However; I am not coaching at this time.>>
A 5th FREE WORKSHOP/ Daily Living.

â We believe that empowering yourself shouldnât just be rewarding, but also really simple (and free). Thatâs why your journey from clicking on a course you want to take to completing it and getting a certificate takes only 6 steps.
Hopefully Before Summer, We can add our courses to the teacher/creator section. It's all within project management and preps right now. So wish us luck.
Check our Website for more info: https://ldmchapels.weebly.com
Get started for Free.

âCurrency is Euro. Courses can be free unlimited. Only pay for your diploma. See Website for xtra assistance.
âMake sure to convert your cash. Online Wallets do vary. I keep my transactions safe as possible. I do prefer PayPal Biz. (See Site for more info.)
Understanding Vibrations
If not experienced, it may seem weird understanding vibes? We start small and by accident. Usually, we learn about vibrations within social. Examples are: That bad vibe you felt. Also, that good feeling you had. These are common situations we often have naturally. We chit chat about it then let it go. However; those are called vibes using your instincts. Then, your senses are called your intuition. We all can develop the gift of intuition and using energy awareness.
Energy Healing
First, Energy healing is universal. This is also true for Reiki as an art and rehab resource. Within the Health Sciences, Rehab has changed dramatically. The term is now very flexible.
Reiki alone, expanded tremendously during the past 3 years. Distant healing is almost more popular than one-on-one sessions? Itâs not a replacement by all means. However, its now easier access online vs local sessions. This does break limit barriers providing instant comfort.
Practice Poses
You can stand within mountain pose Tadasana to get started.
Also, you can start within a lotus Sitting Position to begin a session.
Thereâs no wrong or right way. Maybe if you are rushing, thatâs incorrect lol. The key is being comfortable, calm, at peace. This begins any session.
Also using props like candles, incenses, even going outdoors for fresh air.
(See Presentation for all sections, THX)
Clearing Karma, Letting go.
Now, that you understand more about energies, vibrations, the practice fusions, letâs go deeper. I wanted to make sure you all were comfortable. These sessions are for all levels from beginner to review.
Again See the presentation slides, Thx.MEDICAL BIOLOGY MCQS BY. DR NASIR MUSTAFA

Â
Slides to support presentations and the publication of my book Well-Being and Creative Careers: What Makes You Happy Can Also Make You Sick, out in September 2025 with Intellect Books in the UK and worldwide, distributed in the US by The University of Chicago Press.
In this book and presentation, I investigate the systemic issues that make creative work both exhilarating and unsustainable. Drawing on extensive research and in-depth interviews with media professionals, the hidden downsides of doing what you love get documented, analyzing how workplace structures, high workloads, and perceived injustices contribute to mental and physical distress.
All of this is not just about whatâs broken; itâs about what can be done. The talk concludes with providing a roadmap for rethinking the culture of creative industries and offers strategies for balancing passion with sustainability.
With this book and presentation I hope to challenge us to imagine a healthier future for the labor of love that a creative career is.LDMMIA Reiki News Ed3 Vol1 For Team and Guests
