Metode penelitian yangdigunakan adalah prototyping and assembling. Pembuatan trainer ini meliputi pembuatanperangkat keras (hardware) dan perangkat lunak (Software). Trainer ini memiliki berbagai sensor,output serta modul pengendali berupa Arduino uno. Nilai hasil pengujian dari pembacaan sensorsuara mengunakan handphone dengan besar volume 10, besar nilainya akan berubahtergantung dari jarak. Meskipun pada jarak 25 cm sampai 45 cm nilai tidak berubah yaitu 68.Pengujian sensor jarak menghasilkan nilai sesuai jarak benda. Indikator LED akan menyala ketikajarak lebih dari 50 cm. Nilai pembacaan sensor cahaya akan berubah sesuai intensitas cahayayang diberikan. Indikator LED akan menyala ketika besar nilai lebih dari 600, pada keadaan gelapnilai yang tampil 66 dan keadaan terang 910. Hasil pembacaan pada sensor suhu indikator LEDakan menyala ketika nilai yang tampil lebih dari 30 oC.

At the higher education level in the field of engineering, the development and utilization of educational media for practical learning is needed to ensure that students have technical skills and not just theory. The purpose of this study is to develop practical learning media for the transducer sensor subject and industrial instrumentation in the Multi-Sensor Application Trainer (TAMS). The trainer is based on current developments in transducer sensor technology and control systems. The research method used is research and development (R & D) using a media development model with ADDIE (analysis, design, development, implementation, and evaluation). Developing this trainer includes making hardware (hardware) and software (software). This trainer has various sensors, outputs, and a control module in the Arduino Mega2560 and is supported by the Raspberry Pi. This trainer is equipped with a practicum module that contains 15 (fifteen) practicum that will be used by students. The results of the validity test by material experts obtained an average percentage of the assessment score of 85.25% which means that it is valid and very feasible to use. The results of the validity test by media experts obtained an average percentage of the assessment score of 78.04%, which means that it is valid and very feasible to use. The results of the student's assessment of the use of trainers are 90%, so it can be concluded that the TAMS is very suitable for use. Qualitatively, students considered that the TAMS could function well and be easy to use.
... Typically, the traditional method involves translating lecture content into calculations in paper-based design exercise, which involved doing truth table calculations or Karnaugh mapping for circuitry connection, for example. To support this teaching method, encouraging "learning while doing" approach in system design projects can help students to connect their learned concept from lectures to practical development [6][7][8]. In this case, educational tools can be implemented to improve student understanding. ...
... However, several disadvantages need to be addressed such as fixed wired/not "plug and play", cost effectiveness and difficult development platform. [6] The proposed training module comprised of fixed IC chip which are wired with electronic components such as counter, decoder and display. Several experiments to cater DE syllabus content including combinational logic circuit aims to provide economical learning platform for students. ...
To supplement conventional teaching methods, use of new technology have recently being adapted in the current education system. Such examples are implementing simulators and quiz kits in a classroom session to assist teachers in providing standardized evaluation or practical and more direct examples of concepts that are being taught. Additionally, the well-known issue of attracting student interest in a so-called uninteresting conventional lecture may be solved by using this technological method. The objective of this works to provide methods on developing a prototype training kit (named as e-Logic trainer kit or e-LTK) which comprises of an electronic simulator and quiz assessment module to evaluate subject knowledge on logic gates. The e-LTK is developed by using Arduino Mega 2560 as the base microcontroller, equipped with keypad and display module as the user input/output interface. The quiz assessment module contained in the prototype also allows conversion of inputs by combinatorial logic circuits into output in the form of timing diagram. This equipment enables electrical engineering students to simulate several combinations of logic circuit, reinforcing the understanding of logic circuit operation. The effectiveness of using this prototype in educational settings have been evaluated through a survey on students and instructors at Faculty of Technology in Engineering (FTK) in Universiti Teknikal Malaysia Melaka (UTeM). Response has been positive, with 60% of the correspondence has shown positive feedbacks, indicating the usefulness of the prototype kit.
Despite the presence of E-commerce people prefer to buy many items only in shopping centers for the sake of their own satisfaction. Among the problems faced by the customers one difficulty is waiting on a bill counter after shopping. Though their intent is just to buy one or two items, waiting to bill items results in long ques and consumes time. The shopping environment are ready to welcome any smart machines that can automate the billing process to reduce manpower and time spent for that process. This research developed a system placed on the shopping trolley, which is to complete the billing process in the trolley rather than waiting in long queues. To achieve this all items in the mall should have barcodes printed on them and all shopping trolleys should be equipped with a barcode scanner, weight sensor and LCD screen. When a customer scans any item it its code will be detected automatically, the item weight, cost and name will be displayed on the LCD, thereby the cost gets added to the total bill. If a customer wishes to remove an item trolley, the customer just presses a push button and rescan the item, the amount and weight of that item gets deducted from the total amount. Hence billing can be done in the trolley itself, thereby saving a lot of time and energy for customers or users. The study show that the Barcode has a response time of 2.6 seconds ,with an accuracy of mean square average of 4.46 Manuscript History
Implementation of a complex circuit with hardware components in a conventional way seems to be quite difficult for the students. Resultant wave-shapes may not be accurate and determined values of different parameters may not be exact. Due to inaccurate outcomes and time-consuming process in a conventional way, researchers despond to continue their approach. In this paper, a trainer kit has been developed which is just like a laboratory with necessary components and aims to implement multivibrators (Bistable, Monostable, and Astable) and RC phase shift oscillators in the laboratory. A variable power supply is constructed in the trainer kit that provides 9 V dc to the multivibrators and 15 V dc to the oscillator. Potentiometer, voltage regulator, different active and passive components such as resistors, capacitor, op-amp, transistor, and
numerous jumper wires are introduced in this kit. The trainer kit ascertains an easy implementation by eliminating complexity and assures accurate wave-shapes at the oscilloscope within a short time. To validate the proposed system, a survey program has been introduced among many students and faculty members. The outcome of the survey is the demonstration of student and instructor views and opinions which acknowledges the trainer kit as an efficient and compatible working platform.
