Abstract – This article presents a report on the Procedure, Function, Science, Components required and Precaution to be taken for making a Buzz Wire Game. A game in which a metal loop  has to be guided along a curved length of wire without touching the loop to it. If one accidentally touches the loop onto the wire , you hear a buzz and your chances are decreased by one. It uses a Seven Segment Display, LED, Buzzer Module and Aluminium coil. The method shown in this article can be used to make a simple Buzz wire circuit which can be modulated to one’s preferences.

Introduction 

Buzz wire is a challenging and competitive game. The electric buzz wire game was invented by Robert Scrimshaw in 1953. A Wire Loop Game, or Buzz Wire, is a game which involves guiding a metal loop along a serpentine length of wire without touching the loop to the wire. The loop and wire are connected to a power source in such a way that, if they touch, they form a closed electric circuit. This game is also called a Steady-hand Game or an Electronic Loop Game.

Components

Seven Segment display

A Seven-segment Led is a digital display module specialized to display numerical information. These kinds of displays are widely used in digital clocks, electronic meters, basic calculators, and other electronic devices that display numerical information. It consists of seven segments of light-emitting diodes (LED’s) which are assembled like numerical 8. We can form combinations of display numerical from 0 to 9. There are two types of led 7- segment displays: common cathode and common anode.

Buzzer module

The piezo, also known as the buzzer, is a component that is used for generating sound. A buzzer  is an audio signalling device, which may be mechanical, electromechanical, or piezoelectric. Buzzers and beepers are included in alarm devices, timers, trains. The buzzer has a sound output of 85 decibels. Inside the buzzer there is a membrane, like a drumhead, that vibrates due to electric current.

LED

A light emitting diode (LED) is a semiconductor device, which can emit light when an electric current passes through it. When current passes through an LED, the electrons recombine with holes emitting light in the process. They are used as aviation lighting, fairy lights, strip lights, automotive headlamps, advertising, general lighting, traffic signals, camera flashes, lighted wallpaper, horticultural grow lights, and medical devices.

Aluminum wire

Scientific theory 

This buzz wire game is made up of aluminum wires as it  is a very good conductor of electricity. Electricity flows from the battery through the buzzer, hook, LED, seven segment display, and wire spiral back to the battery. So, when electricity is passed through metals, electrons carry electricity and spread it all over the metal. The mobility of electrons is the reason why metals conduct electricity. Therefore, the buzzer sounds when the metal hook touches the wire spiral  as the circuit gets completed. 

Procedure

First, take the base as wood and paint it black. Then, take an aluminum wire and bend it in a curly wave shape. Fix the aluminum wire to the wood base on both the points by the help of screws. Then solder the ground to one point of the aluminum wire, and hook it to the voltage wire. Then the components such as led, seven segment display and buzzer are placed on the breadboard and are connected to the digital pins in the Arduino uno board by the help of wire. Then, those components have to be coded.

Precautions

Ensure that the ends of aluminum wire is covered to ensure that start and stop does not trigger an error.
