We have included a header file for LCD at the beginning of the code.<\/p>\n<p>2. Next, we initialized arrays and variables that will be required in the function.<\/p>\n<p>3. In the setup function, we have declared the LCD as having 2 rows and 16 columns. Also, we have configured the pin mode for input purposes and began the serial connection with 9600 bits per second.<\/p>\n<p>4. In the loop function, we display the options, along with the question, and give 5 seconds of time to the candidate to give the answer to that question using the push button. If the answer is right, the candidate will get 5 points, and at last, the final score will be displayed.<\/p>\n<h3>Purpose of Functions Used In The Code:<\/h3>\n<ul>\n<li><em><strong>lcd.clear()<\/strong><\/em> function will help to clear the screen of the LCD.<\/li>\n<li><em><strong>lcd.print()<\/strong><\/em> function prints the text in the LCD,<\/li>\n<li><em><strong>lcd.setCursor<\/strong><\/em> function helps to set the cursor in the LCD.<\/li>\n<li>The delay function takes time in milliseconds, using which the candidate will be given 5 seconds of time to answer each question.<\/li>\n<\/ul>\n<h2><a id=\"post-8894-_1fob9te\"><\/a><strong>Output<\/strong><\/h2>\n<p>We will get the following output on the successful completion of this Arduino project.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-18248 size-full aligncenter\" src=\"https:\/\/rudelabs.ai\/blogs\/wp-content\/uploads\/2022\/11\/Math-Test-Using-Arduino.webp\" alt=\"Math Test Using Arduino\" width=\"1054\" height=\"516\" \/><\/p>\n<p>On starting the simulation, we will be able to see the display in LCD and see our final score at the end of the test.<\/p>\n<p>&nbsp;<\/p>\n<p><a href=\"https:\/\/rudelabs.ai\/blogs\/category\/arduino\/\"><em><strong>More Arduino Projects&gt;&gt;&gt;<\/strong><\/em><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Today we will learn how to create a Math Test using Arduino.
