With an Assembled & Tested PCB

DIY kit comes with an Assembled and Tested PCB ensuring 100% output guarantee. Includes hardware for assembling project from scratch. Fully supported by elaborate documentation, audio visuals and tools to independently carry out the project work.

PROJECT DESCRIPTION

The main goal of this project is to develop a fastest-finger-first quiz buzzer system that can be used to recognize the participant who presses the buzzer fastest and first among all in a group of people in a quiz competition by the quiz computation sensor (D-flip-flop).

 This circuit includes 8 numbers of push buttons which are fed to a D-type flip-flop. This flip-flop generates an O/P signal, which is fed to a transistor, making the corresponding LED to switch ON and also generate a buzzer sound.

 This project in future can be enhanced by using a display to indicate the order in which the switches are pressed.

Q & A
Q:  Which microcontroller is used in this project?
A:  The microcontroller used in this project is a 40 pin IC from 8051 family.
Q:  Where is this project used?
A:  This project can be used in crowded areas like temple, bus stations etc,
Q:  How many switches are provided with this project?
A:  About 8 switches are provided with this project, along with 8 LEDs.
Q:  What is the formula for calculating smoothing capacitor value?
A:  There is some approximated formula .Peak to peak ripple voltage = Load current in amps / (2*line frequency in hertz *capacitance in farads). But as rule of thumb for 1 A current 1000uF is best. Thus it is load dependent.

I got to know about edgefx through my friend. He has suggested me to buy the project from edgefx. He gave me the website details. So, i have directly contacted the customer service.
After watching the website i really liked the projects and their presentation that’s why i have decided to buy project from edgefx. I like the presentation of the project.
the project was delivered on time with right components.
i have called the customer service people.They have helped me in purchasing the project.
please provide more and more projects on IRLED. Please provide variety of projects for upcoming engineering students.
I know the there was blog for edgefx called elprocus. In that there was detailed description of components and project. I liked it.
i gave reference to my friends.
