{"product_id":"dtmf-robot","title":"DTMF Controlled Robot without Microcontroller","description":"The \u003cstrong\u003eDTMF Robot kit \u003c\/strong\u003eDTMF stands for \u003cstrong\u003eDual Tone Multi-Frequency\u003c\/strong\u003e, it is the foundation of your phone system. DTMF is the \u003cspan data-mce-fragment=\"1\"\u003egeneric term\u003c\/span\u003e for Touch-Tone (touchtone is a \u003cspan data-mce-fragment=\"1\"\u003eregistered \u003c\/span\u003etrademark of ATT). The phone is technically a DTMF generator that produces DTMF tones as you press the buttons. \u003cbr\u003e\u003cbr\u003eIn this \u003cstrong\u003eKit DTMF Robot\u003c\/strong\u003e tone is transmitted over the remote location and can be heard at the remote location using the mobile communication protocol. This tone can be received through the DTMF receiver and decoded to generate a binary 4-bit sequence that is directly compatible with digital controllers. The system can be used in two ways that directly connect a mobile (through headphones) to the decoder to the control operation at a location or make a call to the remote location mobile connected to the decoder to control the operation. \u003cbr\u003e\u003cbr\u003eThe \u003cstrong\u003eKit Consists Of a Decoder Interface Circuit\u003c\/strong\u003e that consists of the RC combination acting as a tone filter which gives the filtered signal to DTMF decoder IC CM8870 which decodes the frequency to give a 4-bit binary output. The next section is the motor driver circuitry. The control signal for it will be again given by the CM8870 IC to drive the motor while checking the mobile data.\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003e\n\u003cbr\u003eBlock Diagram\u003c\/h3\u003e\n\u003cdiv id=\"p_info\" style=\"text-align: start;\"\u003e\u003cimg alt=\"Block-Diagram-DTMF-Robot-Online\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/DTMF-Robot-Block-Diagram.jpg?v=1632572355\" 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 height=\"400\" width=\"800\" title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/pZ0hhpPUMSU\" frameborder=\"0\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe height=\"400\" width=\"800\" src=\"https:\/\/www.youtube.com\/embed\/6rmErwU5E-k\" 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 height=\"400\" width=\"800\" 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 KIT","offer_id":40708842815669,"sku":"LGKT014","price":999.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE KIT","offer_id":40708842782901,"sku":"LGKT014_R","price":1299.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/DTMF-Controlled-Robot-using-Arduino.jpg?v=1632572450","url":"https:\/\/kitsguru.com\/de\/products\/dtmf-robot","provider":"KitsGuru","version":"1.0","type":"link"}
