All the previous experiment has something to do with LED. However, the circuit in this experiment can produce sound.Normally, the experiment is done with a buzzer or a speaker while buzzer is simpler and easier to use. The buzzer we introduced here is a passive buzzer. It cannot be actuated by itself, but by external pulse frequencies. Different frequencies produce different sounds. We can use Arduino to code the melody of a song, which is quite fun and simple. \u003cbr\u003e \u003cbr\u003eFeatures: \u003cbr\u003e1.Working voltage: DC 3.3V-5V. \u003cbr\u003e2.Interface type: digital. \u003cbr\u003e3.Application: Arduino, 51 singlechip, Raspberry Pi and so on. \u003cbr\u003e4.Come with a light transparent box for easy carry and store. \u003cbr\u003e5.Material: FR4. \u003cbr\u003e \u003cbr\u003ePacking List: \u003cbr\u003ePassive Buzzer Module x 1 \u003cbr\u003ePlastic Box x 1\u003cbr\u003e\u003cbr\u003e","brand":"STARS","offers":[{"title":"Default Title","offer_id":47530467033374,"sku":"US-045346","price":3569.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0834\/9266\/7678\/products\/5d514c21bb7c992dab7be8ca.jpg?v=1702546824","url":"https:\/\/uniqbuy.in\/products\/landatianrui-ldtr-rm021-passive-buzzer-module-for-arduino-black","provider":"UNIQBUY","version":"1.0","type":"link"}
