... 18 The out of the Analog circuit with LM358 is connected to PIC integration's RB0 numbered leg. 19,20 The aim of this is to count the pulses which come through to PIC RB0 numbered for 10 s. During this measurement, it calculates the driver's pulse rate, multiplying the obtained value with 6. ...
This study involves a circuit which is made in order to prevent traffic accidents caused by tiredness of the driver and sleepiness. Infrared light emitting diode and infrared phototransistor are used to track driver’s body values during vehicle driving. The pulse value, which can increase or decrease directly proportional to the heart rate, can be controlled with the help of this infrared light emitting diode and infrared phototransistor. Peripheral interface controller is used in the construction of the system. The blood pressure was transformed to an electronic signal with infrared receiver and infrared transmitter by checking the heartbeats. This electronic signal was processed with peripheral interface controller and the system was constructed. In application, the pulse rate of the driver is continuously measured, and these values are shown on a small display permanently. It is installed on a portable steering wheel which can be used in the automotive industry. The process of waking the driver up can be made by raising the voice of music and with the vibration of the seat.

In this study, a highly instructive and novel remote laboratory platform using up to date software and hardware units is designed to teach main concepts of Electrical Engineering with the help of web-based simulations and remote accessible experiments in real time. Interactive experimental applications for direct current (DC) motors and several electrical circuits are carried out in this study to test the efficiency of the system. First, mathematical model of each simulation is developed in MATLAB and then all models are transferred into .NET platform by means of MATLAB Builder for NE toolbox. A dynamic library for each model is also created using NE toolbox. Then, all libraries are embedded into an interactive web page designed in ASP.NET platform. Data transmission between the server and the real experimental set is established by a microprocessor via the USB port to achieve the experimental studies over the Internet in real time. While remote experiments are being performed, data obtained by the experimental set are simultaneously transferred to the MATLAB. Then, the system generates both graphical and numerical results about the current experiment and all results are sent to a user-friendly web interface to give users some feedback on the experiment.

... Some studies assert that time spent participating in "active learning", such as during experiments, is as important for students as "passive learning", such as when attending lectures. The same outcomes are derived from experimental-or practice-oriented systems [10][11][12]. ...
This study proposes the development and implementation of a novel Universal Serial Bus (USB)-Programmable Logic Controller (PLC), called a USB-PLC controller, for a mechatronics cloud laboratory. The aim of a mechatronics cloud laboratory is to provide state of the art research quality equipment to students, allowing them to conduct hands-on experiments via the Internet. One objective of the cloud laboratory is to not only provide equipment for conducting set experiments, but also to provide a means for students to access research equipment in order to conduct individual research experiments. The proposed controller for these cloud laboratory experiments has been chosen in order to expose the students to as many different engineering and technology disciplines as possible.
In computer science and engineering education, teaching PC interfacing courses and laboratory experiments are strongly required. PC interfacing is the field of developing or simulating real/virtual solutions for exchanging data/commands between PC and the outer world of sensors and actuators. Recently, virtual experiments and Labs have been adopted by engineering educators to preclude the physical presence of students and tutors and to provide effective skills acquisition and hands‐on experience in a virtual manner. High‐cost LabVIEW from National Instruments company is the dominant platform to develop, execute, and animate virtual PC interfacing experiments similar to real ones. This paper presents a toolchain, the course contents, and virtual experiments that cover many different PC interfacing technologies such as UART, SPI, RS232, USB, SD card interfacing, and wireless GSM/GPRS. The virtual nature of VFST toolchain refers to enabling the students to design, animate, and run their prototypes or solutions inside only PC programs without the need to build physical or real ones until making sure of their prototypes' functionality. The main aim of the VFST platform is to make students able to develop C# based applications and to implement solutions with an aesthetic similar to LabVIEW capabilities to become a low‐cost alternative of it. VFST consists of a group of free‐of‐charge and third‐party software programs such as VSPD, Virtual USB driver, WinImage, and Real‐Term alongside with Proteus simulator and C# programming language. This paper presents qualitative and quantitative evaluations of the benefits and effectiveness of VFST. Findings are collected via feedback responses using an online questionnaire survey. These findings clarify that the student cohort is, in general, supportive that VFST Lab's content and virtual experiments have a considerable effect on their career after and before their graduation.
Internet and common communication devices can be very useful enterprise to make use of them in processes that require remote measurement and control. Web and these kinds of devices also use real time applications. Internet is not only used for communication but also used in real time application processes that require remote measurement and control. This system has been successfully tested to the air conditioning channel in web based. In this application circuit has been prepared for controlling the air conditioning channel and receiving data from the temperature sensor by using serial port. Then the control interface software which runs on the computer has been improved in order to supply the interaction between the user and the controlled system. At the end of the study, client computer connect to the controlled system over internet by supplying remote access.
