The project aims at developing an analog and digital clock using the C language that displays an analog and as well as a digital clock. Features of clock using C Graphical clock for better visual appearance Beep sound with dedicated time interval Dedicated function for dedicated work like beep, draw line and frame. The code of Analog and digital clocks is written in TurboC++ environment and may not be supported by other various compilers like DEV C, codeBlock, etc. The source code of the application Analog and Digital clock using…
Read MoreInventory Management System Using C
The project aims at developing an inventory management system using the C language that enables an organization to maintain its inventory. The project inventory management system demonstrates the creation of a user interface of a system, without the use of C Graphics library. The application uses basic C functions to generate menus, show message boxes and print text on the screen. To display customized text with colors and fonts according to application requirements, functions have been created in the application, which fetch the exact video memory addresses of a target…
Read MoreRecord Entry System Using C
The objective of the record entry system is to develop a login-based record keeping system, which has nested menus and different interface for different sets of users. The application record entry system contains separate interface defined for an administrator and employees. The application provides a basic menu, which has menu options for both types of users. According to the selection made by the user, the user is prompted to enter his login name and password. On successfully validation the user name and password, a menu is displayed to the user…

Read MoreSound Operated On-Off Switch
Various remote control-based projects are already posted on bestengineeringprojects.com. Now here is a unique remote control circuit called a sound operated on-off switch and it responds only particular frequency of sound (4.5 kHz) and can control the device from a distance of up to 4.6 meters (15 feet). Most sound-operated switches use clap sound or voice to activate the remote control. Tone frequency generated by clapping or a voice control is not constant and designing a receiver circuit for a particular or ordinary clap or voice is very difficult. To…

Various types of switch circuits like a light operated switch, sound operated switch, etc is already posted on www.bestengineeringprojects.com. Now here is a thermal touch switch that automatic on and off due to the increase and decrease of pre-defined temperature. This type of circuit is useful to operate fans, cooler, etc. Circuit description of thermal touch switch using operational amplifier 741 The circuit comprises an operational amplifier IC (IC1), silicon diode (D1 and D2), and a few passive components to complete the circuit. Diode D1 is used here as a…
Read MoreVoltage into Frequency Converter Circuit using 741 IC
IC 741 is the most used and popular operational amplifier IC, because of its unique feature and low price. Various op-amp 741-based projects are already posted in the operational amplifier-based projects section. Now, here is a simple project using a couple of op-amps 741 IC called voltage into frequency converter. Description of voltage into frequency converter Circuit using 741 IC The circuit of voltage into frequency converter consists of a couple of op-amp 741, a couple of transistors, and a few passive components (resistors). The voltage of 0.5V to 15V…
Read MoreTelephone Diary using C++
The project telephone diary using C++ stores contact information of person. The program telephone diary has used file system to store contact information in disk. It stores ID, Name, Address, Phone, Mobile and Email of a person. This project allows us to add, update, delete and search particular record of person. We can search contact information from person name and mobile number. Again, we can list out all contact in alphabetical order choosing appropriate option in program. Again, we can update and delete existing contact information on the basis of…
Read MoreEmployee Management System Using C++
Introduction to Employee Management System Using C++ Employ management system using C++ is a menu-driven program that allows us to add, update, delete and search records of an employee working in an organization. The program employee management system stores employee ID, name, post, department, and salary of the employee. Initially, it has no data. Thus, we have to add employee records choosing appropriate options in this program (i.e. selecting option #1). Previously we had posted Employee Management System Using C with the same features. Employee Management system using C++ program…
