{"product_id":"piano-based-on-555-timer","title":"Piano Based on 555 timer","description":"A simple electronic toy piano can be easily constructed using the \u003cstrong\u003epopular 555 timer IC.\u003c\/strong\u003e This 555 Timer can be easily wired as Astable Monostable or Bistable multivibrator. The heart of this circuit is a \u003cstrong\u003e555 timer IC\u003c\/strong\u003e. The 555 timers are operated in a stable multivibrator mode. In a stable multivibrator mode, the circuit produces accurate free-running waveforms, which can be adjusted. There are 8 buttons connected in the circuit.\n\u003cp\u003e\u003cbr\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003cstrong\u003ePiano Based on 555 timers Kits\u003c\/strong\u003e \u003c\/span\u003eproduces a tone. Similarly, six buttons produce six different tones. That means, it just works as a toy piano. When the first button from the right is pressed it produces a high pitch tone. When the last button is pressed it delivers a low tone. This \u003cstrong\u003ePiano Based on 555 timers\u003c\/strong\u003e is because of the resistance connected to the buttons. The low threshold voltage obtained at the sixth pin slows the charging and discharging of the capacitor at the speaker. As the resistance value increases voltage at the threshold pin decreases and low frequency passes through the speaker.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eCircuit Diagram\u003c\/h3\u003e\n\u003cdiv style=\"text-align: start;\" id=\"p_info\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/Piano-Based-on-555-timer.jpg?v=1633601081\" style=\"float: none;\" alt=\"Piano-Based-on-555-timer-circuit-diagram\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cbr\u003e\u003cbr\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 : 15 x 12 x 5\u003c\/li\u003e\n\u003cli\u003eWeight (gm): 50\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cbr\u003e\u003cbr\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\/SCmhqCBaJzI\" 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\u003cbr\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/wMqj6D6YZB4\" 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\u003cbr\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe width=\"800\" height=\"400\" src=\"https:\/\/www.youtube.com\/embed\/W6mixXsn-Vc\" 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":40708939907253,"sku":"LGBK002","price":99.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/diy-piano.jpg?v=1633602626","url":"https:\/\/kitsguru.com\/de\/products\/piano-based-on-555-timer","provider":"KitsGuru","version":"1.0","type":"link"}
