{"product_id":"digital-code-lock-circuit","title":"Digital Code Lock Circuit","description":"This \u003cstrong\u003eDigital Code Lock Circuit \u003c\/strong\u003eis a simple but effective code lock circuit that has an automatic reset facility. The circuit is made around the dual flip-flop IC CD4013. Two CD 4013 ICs are used here. Push-button switches are used for entering the code number. One side of all the push button switches is connected to +12V DC. The remaining end of push buttons 2,3,6,8 is connected to the clock input pins of the flip-flops. The remaining end of other push button switches is shorted and connected to the set pin of the flip-flops. \u003cbr\u003e\u003cbr\u003e The relay coil will be activated only if the code is entered in the correct sequence and if there is any variation, the lock will be resettled. Here is correct code is 2368. This \u003cstrong\u003eDigital Code Lock Kit \u003c\/strong\u003emakes the lock open for a fixed amount of time and then it locks automatically. The time delay can be adjusted by varying the values of resistance and capacitance. \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=\"Digital-Code-Lock-block-diagram\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/Digital-Code-Lock.jpg?v=1633516516\" 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\/SiyGpn_3XI8\" 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\/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 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":40708891115701,"sku":"LGKT130","price":549.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE","offer_id":40708891148469,"sku":"LGKT130_R","price":699.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/digital-code-lock-using-arduino.jpg?v=1633516865","url":"https:\/\/kitsguru.com\/fr\/products\/digital-code-lock-circuit","provider":"KitsGuru","version":"1.0","type":"link"}
