Sound Operated On-Off Switch

Engineeering Projects
circuit diagram of electronic clapper

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…

Employee Management System Using C++

Engineeering Projects
main menu of Employee 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…
