In the beginning, we included the header file IRremote.<\/p>\n<p>2. After that, we initialized the LEDs to integer values 12,10,8 and 6, respectively, which denotes the pin number to which they are connected in Arduino Uno. Also, we have declared the IR_Sensor variable to pin number 2.<\/p>\n<p>3. After that, we used the IR library function and variable.<\/p>\n<p>4. Now, after this, we have used two functions, that is, setup and loop.<\/p>\n<p>5. In the setup function, we have declared that we are using LEDs pin numbers for output purposes.<\/p>\n<p>6. The serial.begin() is for enabling serial communication between Arduino and remote.<\/p>\n<p>7. In the loop function, we are using the if statement; if some input is received, it will store its value of it in the value variable.<\/p>\n<p>8. Now, to know which LED we need to glow on which value, we have used a switch case.<\/p>\n<p>9. Inside the switch case, if a particular value is there, we make that LED high for some time and then again make it low.<\/p>\n<p>10. We are doing it using a delay function, which takes time in milliseconds.<\/p>\n<p>11. Atlast, to continue it further, we have used the last function to receive the next value.<\/p>\n<h2><a id=\"post-8933-_heading=h.1fob9te\"><\/a><strong>Output<\/strong><\/h2>\n<p>We will get the following output on the successful completion of the project Control LEDs Using an IR Remote With Arduino.<\/p>\n<p>Click any of the first four switches;<\/p>\n<ul>\n<li>On clicking 1 numbered switch, the first LED will glow,<\/li>\n<li>On clicking switch number 2 from the IR Remote, Red LED turns on.<\/li>\n<li>On clicking switch number 3, the green LED will glow, and<\/li>\n<li>On clicking the 4 numbered switch, the white LED will glow.<\/li>\n<\/ul>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-18233 size-full\" src=\"https:\/\/rudelabs.ai\/blogs\/wp-content\/uploads\/2022\/11\/Control-LEDs-Using-an-IR-Remote-With-Arduino.webp\" alt=\"Control LEDs Using an IR Remote With Arduino \" width=\"1045\" height=\"536\" \/><\/p>\n<p>Thus, using this, we don\u2019t even need to go there to turn on the LEDs.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In this Arduino tutorial, we will learn how to Control LEDs using an IR remote with Arduino This comes under IoT (Internet of Things).<\/p>\n","protected":false},"author":1,"featured_media":8934,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"categories":[31,7],"tags":[],"class_list":["post-8933","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-arduino","category-coding-projects"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.1.1 -
