It is the material of choice for assembly work, skill training, etc.\u003cbr\u003eThe core of this breathing light circuit is the LM358, which includes two independent, high-gain, internal frequency-compensated dual operational amplifiers. Together with the external circuit, it forms a more accurate bistable circuit. R1 and R2 form a double. The reference voltage divider of the operational amplifier is 6V. R3 is the operational amplifier feedback resistor. C1, R4, R5, R6, and W1 determine the frequency of the breathing lamp. This circuit is adjusted by W1.\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-size: 16px;\"\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003eWorking voltage: 5V\u003cbr\u003ematerial: metal\u003cbr\u003eColor: brown\u003cbr\u003eSize: 45*32mm\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-size: 16px;\"\u003e\u003cstrong\u003ePackage Included:\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e3 x  Electronic Production Kit\u003c\/span\u003e\u003cbr style=\"font-size: 13.3333px;\"\u003e\u003cimg alt=\"\" src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/ser1\/banggood\/images\/E3\/56\/c1b39bfc-5d67-4265-b724-b089de5d5e4a.jpeg\" style=\"font-size: 13.3333px;\"\u003e\u003cbr style=\"font-size: 13.3333px;\"\u003e\u003cbr style=\"font-size: 13.3333px;\"\u003e\u003cimg alt=\"\" src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/ser1\/banggood\/images\/BE\/68\/b7a13d39-d33e-4121-92a7-6f377b58b90e.jpeg\" style=\"font-size: 13.3333px;\"\u003e\u003cbr style=\"font-size: 13.3333px;\"\u003e\u003cbr style=\"font-size: 13.3333px;\"\u003e\u003cimg alt=\"\" src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/ser1\/banggood\/images\/07\/D4\/85fe54ef-f468-4835-b19c-65235e5d2427.jpeg\" style=\"font-size: 13.3333px;\"\u003e\u003cbr style=\"font-size: 13.3333px;\"\u003e\u003cbr style=\"font-size: 13.3333px;\"\u003e\u003cimg alt=\"\" src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/ser1\/banggood\/images\/48\/BA\/73923d4c-74ed-4393-b4f2-64c510ce3c9f.jpeg\" style=\"font-size: 13.3333px;\"\u003e\u003cbr style=\"font-size: 13.3333px;\"\u003e\u003cbr style=\"font-size: 13.3333px;\"\u003e\u003cimg alt=\"\" src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/ser1\/banggood\/images\/59\/91\/eb4b03ab-bcc3-4b99-aad1-e49d78e38307.jpeg\" style=\"font-size: 13.3333px;\"\u003e\u003cbr style=\"font-size: 13.3333px;\"\u003e\u003cbr style=\"font-size: 13.3333px;\"\u003e\u003cimg alt=\"\" src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/ser1\/banggood\/images\/3C\/B8\/39a77226-afae-4354-ad78-2c53603893f7.jpeg\" style=\"font-size: 13.3333px;\"\u003e\u003cbr style=\"font-size: 13.3333px;\"\u003e\u003cbr style=\"font-size: 13.3333px;\"\u003e\u003cimg alt=\"\" src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/ser1\/banggood\/images\/0F\/21\/d124da13-f012-42cd-bf24-7be2439a068b.jpeg\" style=\"font-size: 13.3333px;\"\u003e\u003cbr style=\"font-size: 13.3333px;\"\u003e\u003cbr style=\"font-size: 13.3333px;\"\u003e\u003cimg alt=\"\" src=\"https:\/\/imgaz.staticbg.com\/images\/oaupload\/ser1\/banggood\/images\/D3\/AF\/bc9c90a6-beb5-4c4c-b920-1b4a25797fd7.jpeg\" style=\"font-size: 13.3333px;\"\u003e","brand":"Electronic Pro","offers":[{"title":"Default Title","offer_id":35368687272092,"sku":"1648604","price":293.43,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2787\/9162\/products\/2b445a8a-40ba-4310-8697-87a51ef18248.jpg?v=1596625085","url":"https:\/\/electronic-pro-south-africa.myshopify.com\/products\/3pcs-lm358-breathing-light-parts-led-flash-light-electronic-diy-production-kit","provider":"Electronic Pro ","version":"1.0","type":"link"}
