first using · Fastest Finger First Mini Project using Microcontoller ( pdf,doc,ppt) fastest, fastest finger first using 89c51 project, project on fastest. I have designed the circuit using microcontroller, which scans the First step is designing the circuit. The microcontroller used in this case is AT89C51, an 8 bit microcontroller manufactured by Atmel (now Microchip). Quiz buzzer circuit operation using microcontroller (AT89C51) and timer for The team that presses the buzzer first is given the first preference for answering a question. buzzer.

Virgin Galactic — Commercial Space Flight.

It poles all switches within 15 usingg, and displays the result on LCD. The USB interface is one of the solution This project deals with the control circuit for the switched mode power supply and is a combination of a microcontroller and a FPGA.

Fastest Finger First Indicator

Gases like LPG, butane and propane ar This will cause no bus conflicts on the data lines. The connections of the seven segment, input pins and output pins is shown in the circuit diagram. Here we have not used internal software delay which is not variable externally once the program is written. Basics, Usage, Parameters and Applications. In many applications, it is necessary to supply constant dc voltage. Priority encoder IC4 encodes the active-low input condition into the corresponding binary coded decimal BCD number output.

In TV shows, where the whole event is recorded, the actions are replayed in slow motion to detect the first hit. Arduino based GPS receiver.

It is build around microcontroller AT89C This device is capable of distinguishing between two events with a time gap of microseconds. These data lines are connected to port – 3 of microcontroller. There are a total of nine input pins. This project is an electronic display system that is affordable by the colleges and even individuals. R and C are the timing components which decide the duration of the low going pulse. The audio alarm generator comprises clock oscillator IC7whose output drives a loudspeaker.

Social Facebook Twitter GooglePlus. There are a total of nine input pins. There is a wide range of cheap low-voltage motors available, run Tuesday, January 1, Output of rectifier contains pulsating dc which can be removed by use of filter circuit. At times it becomes very difficult to identify which team has pressed the button when two teams press the buzzer within a very small time gap. A buzzer is also sounded for a small duration to give an acoustic alarm.

Design Guides Product Development: Top 20 Computer Engineering Projects. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C51 is a powerful microcomputer which provides a highly-flexible and cost-effective solution to many embedded control applications. The IC78XX series of 3 terminal regulators are available with fixed positive voltages.

The 2 line x 16 character LCD modules are available from a wide range of manufacturers and should all be compatible with the HD Transformer can provide upto mA current.

Fastest Finger First – Final Year Project ~ Engineering Final Year Projects

As soon as fastfst-finger-first one of the inputs is pressed, the buzzer sounds for a small duration. The project is useful for 8-team quiz contest, although it can be modified for more number of teams.


Eight pins of port P2 fastest-finger-fkrst the microcontroller are corresponding to eight inputs and one stop pin for resetting the buzzer system.

On the output side a seven segment is connected to display the corresponding output number. This blogs is an effort to club the scattered information about engineering available in the web.

Step down Transformer specifications: This quiz buzzer disables the other inputs as soon as the first buzzer is pressed. This device has provision of avoiding key bouncing while the inputs are given. The microcontroller keeps scanning the input pins. This project aims to measure the RPM and controls the speed of motor. Fastest-fiinger-first the controller accepts the inputs for TON seconds only and then processes them to give the desired output. It is used for amplification and switching purposes.

Awesome Timer IC Projects. Sometimes two or more players hit the buzzer almost simultaneously and it is very difficult to detect which of them pressed buzzer first. The system uses 8 SPST switches.

Each switch is given to one team. Monostable multivibrator acts as a timer. Power Bank for Smartphones.
