{"product_id":"vibration-alert-system-for-dumb-and-deaf","title":"Vibration Alert System for Dumb and Deaf","description":"This\u003cstrong\u003e Vibration Alert System kit\u003c\/strong\u003e design for only those person who is physically dumb and deaf. Many Deaf people do not use a spoken language, thus they are technically “mute”. The heart of this circuit is a MIC. The MIC detects the noise intensity and generates an analog voltage. \u003cbr\u003e\u003cbr\u003eThis \u003cstrong\u003eDumb and Deaf Analog Variation\u003c\/strong\u003e is converted into digital form using a dual op-amp IC LM358. The op-amp is used as a comparator in the inverting mode to do so. In this operation, we set a reference voltage with the preset 10k (potentiometer) which is connected to pin 2 of IC, and by using preset 10k we can adjust. The output from the LM358 i.e. from pin no 1 drives the vibration motor.\u003cbr\u003e\u003cbr\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=\"Vibration-Alert-System-for-Dumb-and-Deaf-block-diagram\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/Vibration-Alert-System-for-Dumb-and-Deaf.jpg?v=1633500763\" 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\/KfknOFj4UP4\" 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 width=\"800\" height=\"400\" src=\"https:\/\/www.youtube.com\/embed\/Fp37DPZVdRI\" 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\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"DO IT YOURSELF","offer_id":40708951343285,"sku":"LGKT119","price":349.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE","offer_id":40708951376053,"sku":"LGKT119_R","price":499.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/vibration-alert-system-for-the-deaf-project.jpg?v=1633501304","url":"https:\/\/kitsguru.com\/es\/products\/vibration-alert-system-for-dumb-and-deaf","provider":"KitsGuru","version":"1.0","type":"link"}
