Quickest finger first indicators (FFFIs) deliver precision to quiz video games, measuring contestants’ response occasions with accuracy. Supporting as much as eight groups, the system identifies the primary to press their button whereas locking out others. A P10 LED show module highlights the successful crew in real-time.
The system employs an Arduino Mega, designed for setups with eight or extra gamers. Its capability might be expanded to assist over 30 gamers by modifying the code to deal with further inputs. The elements required are listed within the Invoice of Supplies desk. Fig. 1 shows the prototype.
Quickest Finger First Recreation Circuit
Fig. 2 reveals the circuit diagram of the quickest finger-first system. It’s constructed round an Arduino Mega (MOD1), P10 LED show/dot matrix LED show (MOD2), push buttons (SW1-SW8), two energy provides—one for the P10 single-colour show and the opposite for the Arduino Mega—and some different elements.

The quickest finger-first methodology entails candidates urgent a key positioned in entrance of them. The primary individual to press the secret is granted the chance to reply the query.
On this setup, an Arduino Mega constantly screens eight push buttons, every representing one of many eight candidates. The system identifies which button is pressed first. The button variety of the candidate who presses the button first is displayed on an LED display to point the winner. Urgent the reset button constructed into the Arduino Mega board returns the show to its preliminary state, prepared for the subsequent spherical.
The P10 show is related to the Arduino Mega by way of SPI pins. Fig. 3 reveals the P10 LED show and its pinouts for connection.
