This paper focuses on the design and implementation of a Smart Trolley Shopping in supermarkets to solve difficulties of customers whilst waiting in queues for billing.  The trolley is designed to develop market services and make them modern, healthy and easy to use. The remote controls the movement of the trolley automatically and reduces the load on the client during pulling the trolley. In addition, it helps in saving money by not buying unwanted products, with the help of the Liquid Crystal Display  in the trolley, which shows on the update of purchase limit. In this work the client writes the amount they have via the keypad, where the amount appears on the liquid crystal screen. The product used is then checked for price and RFID details. This information is sent to RFID in the product via radio to RFID reader which determines the radio waves. It has an antenna bar for receiving and transmitting data. It also contains a small memory for detailed information of up to 256 bytes. The total cost is summarized by the scanner for materials stored in memory, sent to Arduino. The cart moves according to the client's movements when shopping and then moves to the left, right, forward, backward, or even stops through the buttons. If the customer purchases the products more than the amount recorded on the keyboard, an alarm will serve as a reminder to the customer that he/she has exceeded the purchase limit. The smart trolley is characterized by the speed of accounting compared to conventional accounting and provides a quality  service. It reduces congestion  at the cashier counter and shortens the time and waste of effort during the accounting process.

Set Value

The present system relates to an RFID based shopping system. The system comprises of an RFID reader and various RFID tags are attached to various products. When we go for shopping in supermarkets or malls we select different items according to our choice and put them into a cart and then go to the billing counter for payment, So at the end we get to know about the overall total cost of the products and for sometimes we also have to stand in a queue for a long time resulting in wastage of time for customers. It is needed to develop a system which provides comfort, expediency and efficacy during shopping. The system consists of a Liquid Crystal Display which is mounted on trolley for displaying the information of the selected product and total amount. On 4X4 matrix keypad buyer can set their budget amount for shopping, thus when the total bill amount. If the total bill amount increases than the set value then an alert is generated by the buzzer. After the completion of shopping one can pay the bill by pressing a button wirelessly. Therefore, the system expedites faster billing with reduced time.

Valuable Thing

The most valuable thing in today’s world is time, people are referring those things which consumes less time. Billing in Shopping mall takes lot of time. Billing of products from mall is quite difficult because it takes more time as people have to wait for a long time in a queue for billing .Looking at the advancement in technology, we came up with an innovative idea of “Smart Shopping Cart for Automatic Billing in Supermarket”. This project consists of RFID reader, motion detector sensor, Liquid Crystal Display, push buttons, switches . If user wants to use smart trolley functions then start button should be pressed. When a user put some product in trolley then its code will be detected using RFID reader and cost of a product added to the list and sensor will sense the direction of motion of the product for fault detection and buzzer will be on if fault detected. In case, if user wants to remove some product then user should press the remove switch and product code will be detected by RFID reader and again for any false activity buzzer will be on. At last, counter with least number of queues will be detected and displayed on the cart LCD.

Design Ideas

The single chip microcomputer with digital clock has been designed based on AT89C52, through the design ideas of multi-function digital clock, we have described the system hardware, software and the realization process.The display design and implementation of a year, month, day, time and second is achieved using C language. And the simulation is used by Proteus software. By comparing the actual clock, we have found out the source of the error and have determined the method of adjusting error, and we reduce the error as much as possible, so we can achieve the allowable error range for a practical digital clock in this system.

Final Work

Every tertiary academic institution has the obligation of recording and taking the attendance of its students during lecture periods. Over the years the process and accuracy of this attendance has been marred by many challenges which range from the cumbersome nature of paper sheets used in recording, to the manipulation of attendance by unscrupulous students and so on. This paper is aimed at designing and implementing a biometric students’ time and attendance logging system that helps in mitigating these challenges. This biometric student time and attendance logging system uses the fingerprint biometric characteristics to accurately identify the student. The system also generates a report showing the number of times a particular student was present or absent in a semester. This feat was achieved through the use of an atmega328P microcontroller, a fingerprint RS305 module, a liquid crystal display (LCD), a Red Green Blue (RGB) light emitting diode (LED) and a Personal Computer (PC) amongst others. The software used in this work was developed using visual studio C# and MySQL2008, and the final work was simulated using proteus before it was constructed and tested. The results of the test show a significant improvement over the manual attendance system.

Sistem kontrol pengisian air otomatis dengan dua sumber suplai berbasis mikrokontroler merupakan sebuah sistem yang dapat digunakan untuk mengendalikan level air pada sebuah bak penampungan secara otomatis. Bahan dan alat yang digunakan dalam sistem kontrol berupa mikrokontroler ATmega 8535, sensor air, downloader DI-USB AVR ISP V2/DI-USB to Serial TTL, liquid crystal display, transisor, resistor, pompa air, adaptor 12 volt dc, saklar, dan program editor code vision avr. Metode yang digunakan dalam pembuatan sistem kontrol pengisian air otomatis ini adalah melakukan percobaan dan ujicoba peralatan secara langsung. Sistem kontrol ini bekerja dalam dua kondisi yaitu ketika air dalam bak penampungan melewati batas bawah maka bak penampungan akan terisi secara otomatis dan ketika telah mencapai batas atas yang ditentukan maka suplai air ke bak penampungan akan berhenti, selanjutnya ditambah pengaturan dari dua buah sumber air sebagai suplai yang akan bekerja sesuai dengan prioritasnya. Proses tersebut dilakukan oleh sensor bagian input yang berupa sensor air pada masukan sumber air yang kemudian diproses oleh mikrokontroler terprogram. Hasil percobaan menunjukkan sensor air berhasil memberikan logika Low atau High pada keluarannya sebagai fungsinya untuk memberikan sinyal masukan pada port mikrokontrol. Pada kondisi high, sensor air mampu memberikan nilai tegangan 4,89 Volt DC untuk digunakan sebagai masukan mikrokontroler. Dan pada kondisi low, sensor air mampu memberikan nilai tegangan 0,11 Volt dc sebagai masukan mikrokontroler ketika elektroda tehubung dengan common oleh media air. Driver Masukan terbukti dapat digunakan untuk menggendalikan kerja dari motor pompa 220 V AC dan lampu indikator 12 V DC. Hasil yang dari sistem kontrol pengisian air ini adalah terjadinya pengurangan kerugian yang ditimbulkan karena masalah ketersediaan air dan juga mempermudah kegiatan dalam pengendalian ketersediaan air. Kata kunci : Sistem kontrol, pengisan air otomatis, mikrokontroler, sensor air.
