Fastest Finger First Circuit For Quizzes | 555 Timer Project #17
HTML-код
- Опубликовано: 12 апр 2021
- A tutorial on how to make a fastest finger first circuit which can track the first person to press the trigger. This circuit consists of multiple replicas of a module, each of which can be assigned to a single quiz taker or a team. Each module contains a trigger (We used momentary push button in the video) and an LED indicating whether the team corresponding to this module is the first one to press the trigger.
Monostable arrangement can be coupled to the output of this circuit so that a buzzer beeps for a second after the first press by any quiz taker.

Components Required For Each Module:
* 555 Timer IC
* Momentary Push Button Switch
* PN Diode (I used 1N4148)
* LED + Series Resistor (270R)
* 10K Resistor
Components Common For All Modules:
* 2 x 1K Resistors
* LED + Series Resistor (270R)
* Momentary Push Button (For resetting)
* Breadboard
* Few Breadboard Connectors
* (5-12)V Power Supply

This channel is a hidden gem
Yes.....very true
Awesome, thats exactly what I was after
This is really great!
Thank you for making videos again. Best wishes
Thanks so much! I love your videos!
You're welcome!
Nice
Can u pls provide circuit diagram for buzzer circuit or atleast provide values of resistors nd capacitors used in buzzer circuit
Yes please
you are awesome....great.....
what is the values of the components(resistor, capacitor, etc.) used in buzzer circuit....please answer ASAP
Sir, what are the values of capacitor? Which was shown at the end of the video
Can u please tell the value of Resistor placed in series, and the value of Voltage source
Same problem
you are the best
very nice circuit
Can you please make a video using oled display!!!
Can we use In4007 diode instead of In4148
Please make tutorial for final year projects 🙏
Sure
Hi
What was your final year project?
Can you please tell me a theme to present this project 🤗
How the monostale arrangement is made??
👍👌
Can you give the schematic for rhe monostable?
Will you please make a signal or network jammer 🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳💯💯💯💯💯💯💯💯❤️❤️❤️❤️❤️❤️😃😃😃😃😃
I'll try, but I think there are many videos already
@@elonics yes please make a signal/network jammer please sir
Unfortunately, if two or more players press the button at EXACTLY the same instant, more than one LED can light which is an invalid state.
Bro is this project worth doing.. does it work properly?
@@santhosh4832As mentioned earlier, it IS possible for more than one LED to light if the players' switches are pressed at exactly the same time. I have made a fix for this invalid state. Using three AND gates to monitor LEDs1 & 2; 1 & 3; 2 & 3, then feeding these outputs to an OR gate, the final output can be used to drive an NPN transistor to pull the RESET bus low. This removes the invalid state.
Plz tel me the values of capacitora or resistors used in buzzer circut
Plz anser me
Sir, is it okay just put 3 players not 4 players?
Where are circuit diagrams used?

Thank you for you show me.
First comment ❤️👍
Is this monostable or astable
Monostable
