<p >This is going to be a fun and simple project. You would have heard of the Buzz Wire, a steady hand game, and today you will be learning to make one using Arduino.</p><figure><img src=https://projects.arduinocontent.cc/8b7e97c8-235f-4316-a70c-faba0352c2b9.jpg /><figcaption> </figcaption></figure><h3 ><span >Hardware components used in this project</span></h3><ul ><li >Arduino Nano</li><li >Solderless Breadboard - Mini and Full-size</li><li >LEDs (x2) - Green and Red</li><li >Resistors (x2) - 220 Ω</li><li >Active Buzzer module (KY-012)</li><li >LCD display module with I2C interface - 16x2</li><li >Male-to-Male Jumper wires (x4) - 10cm</li><li >Female-to-Male Jumper wires (x5) - 20 cm</li><li >Jumpers (x5) - to reduce the usage of wires</li></ul><h3 ><span >Hand tools and other essentials</span></h3><ul ><li >Copper wire</li><li >Tape (or any form of insulation)</li><li >Cutting Plier</li><li >Round Nose Plier</li></ul><h3 ><span >Setup</span></h3><div id="gallery"><img id="gallery" src=https://projects.arduinocontent.cc/6dab276e-8f07-44f2-8ebf-736aee301dcd.jpg /><figcaption> </figcaption><img id="gallery" src=https://projects.arduinocontent.cc/adba3834-e450-44f4-b685-d3da2cd0f4f6.jpg /><figcaption> </figcaption></div><p >Your hardware setup must look somewhat similar to the ones in the images above.

You can download the.ZIP version of this library from GitHub by following the hyperlink. To add this.ZIP folder to your Arduino IDE, go to sketch----> include library---->Add.ZIP library. Set the LCD address  to 0x27 for a 16 chars and 2 line display. You can use the </span><a href="https://playground.arduino.cc/Main/I2cScanner/">I2C scanner </a><span >to get the address of your LCD display module.</span></p><p >Create a global variable named 'count'. Within void setup( ) function, use pinMode( ) function to declare the pins of the LEDs and active buzzer as OUTPUT and the wire maze as INPUT. Use lcd.print( ) function to make your LCD display the message, 'Welcome'. Set a delay period of 2 seconds.</p><p >If the loop touches the wire maze, there is a connection between them and it sends a HIGH signal to the Arduino microcontroller. The count will increase, the red LED will light up and the buzzer will give out an alarm sound when the HIGH signal is received. The green LED will light up when the LOW signal is received.</p><p >Use lcd.clear( ) to clear your LCD display and print "Hit count: " in the first row. The number of counts must be displayed in the second row. If the number of counts reaches 5, the red LED and buzzer should be set HIGH and the LCD must display 'You lost!".</p><p >Please watch the YouTube video in the last section of this page to learn how this project works.</p><p >If anyone has any questions with the coding, please feel free to comment below.</p><h3 ><span >Final Look</span></h3><div class="se-component se-video-container __se__float-none" contenteditable="false" style="width: 100%;"><figure style="width: 100%; height: 56.25%; padding-bottom: 56.25%; margin: 0px;"><iframe frameborder="0" allowfullscreen="" src="https://www.youtube.com/embed/l1FxtpqNMyI" data-proportion="true" data-percentage="100%,56.25%" data-size="100%,56.25%" data-align="none" style="width: 100%; height: 100%;" data-index="0" data-file-size="0" data-origin="100%,56.25%"></iframe></figure></div><p > If anyone has any questions, or suggestions, about this project, don't hesitate to comment below.</p>
