{"product_id":"led-based-running-display","title":"LED Based Running Display","description":"\u003cp\u003eThe\u003cstrong\u003e LED-based running display\u003c\/strong\u003e creates an eye-catching running display effect using LEDs. It can be used to light up borders of animations, pictures, etc, and also for short word displays. In this project, we have used some simple components like \u003cstrong\u003e555 timing IC,\u003c\/strong\u003e Decade Counter IC CD4017, and transistors.\u003cbr\u003e\u003cbr\u003eThe \u003cstrong\u003ekit-led-based running display\u003c\/strong\u003e uses IC NE555 and a popular decade counter IC CD4017. This display consists of 16 LEDs of four layers. The  NE555 is wired as an astable multivibrator whose output triggers the CD4017 counter. On powering up the circuit, the timer starts to oscillate to produce triggering pulses. These pulses trigger counters IC 4017 and it counts from 0 to 5. These outputs are fed to general purpose NPN transistors BC547 which are used as current drivers for each led layer. As each of the counter outputs goes high, the corresponding led layer glows sequentially. After it counts up to 4 values it resets to zero and the process repeats.\u003c\/p\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eBlock Diagram\u003c\/h3\u003e\n\u003cdiv style=\"text-align: start;\" id=\"p_info\"\u003e\u003cimg alt=\"LED-Based-Running-Display-block-diagram\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/LED-Based-Running-Display.jpg?v=1633077203\" style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eDimensions (cm) L x W x H : 20 x 15 x 5\u003c\/li\u003e\n\u003cli\u003eWeight (gm): 200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eProduct Video\u003c\/h3\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe width=\"800\" height=\"400\" src=\"https:\/\/www.youtube.com\/embed\/KFmIDVxaZ94\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/6rmErwU5E-k\" height=\"400\" width=\"800\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/Fp37DPZVdRI\" height=\"400\" width=\"800\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"DO IT YOURSELF","offer_id":40708847337653,"sku":"LGKT087","price":449.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE","offer_id":40708847370421,"sku":"LGKT087_R","price":599.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/Running-LED-Display-Board.jpg?v=1633077462","url":"https:\/\/kitsguru.com\/fr\/products\/led-based-running-display","provider":"KitsGuru","version":"1.0","type":"link"}
