{"product_id":"led-chaser-with-variable-speed","title":"LED Chaser with Variable Speed","description":"This project is based on LED flashing, If you want to build a 10 \u003cstrong\u003eLED Chaser Circuit\u003c\/strong\u003e we suggest you this circuit first. It uses popular IC-4017, decade counter and IC-555. It is made of high-quality material and it is more convenient and useful.\u003cbr\u003e\u003cbr\u003eWhen we power the \u003cstrong\u003eVariable Speed LED Chaser\u003c\/strong\u003e circuit, LEDs start glowing one by one for a defined time period. Means first LED Q1 glows and then Q2 glows and Q1 turned OFF and then Q3 glows and Q2 turned OFF and so on. When we change the resistance of the variable resistor then the speed of LEDs increases. Because the frequency of the 555 timer increases and this increases frequency signal is directly connected to the counter’s trigger pin. So that counter changes its state faster.\u003cbr\u003e\u003cbr\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eBlock Diagram\u003c\/h3\u003e\n\u003cdiv id=\"p_info\" style=\"text-align: start;\"\u003e\u003cimg alt=\"LED-Chaser-with-Variable-Speed-block-diagram\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/LED-Chaser-with-Variable-Speed.jpg?v=1632988121\" 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 title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/Oi7GDVQczeU\" 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\/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":40708884857013,"sku":"LGKT078","price":499.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE","offer_id":40708884889781,"sku":"LGKT078_R","price":649.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/led-chaser-circuit.jpg?v=1632988351","url":"https:\/\/kitsguru.com\/fr\/products\/led-chaser-with-variable-speed","provider":"KitsGuru","version":"1.0","type":"link"}
