After pressing the switch, the LED lights flash rapidly in turn, and randomly stays after a few seconds. One of the LEDs is on and the other LEDs are off. This formed a lucky turntable.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e Principle of the circuit:LED electronic lucky turntable consists of NE555 multivibrator and CD4017 decimal counter \/ pulse distributor. 10 light-emitting diodes simulate a lucky object.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e Welding skills:The resistor does not distinguish between positive and negative electrodes; the long pin of the capacitor is positive; the long pin of the LED are positive; The integrated circuit is first installed with a socket, and the chip is installed after the circuit is completely installed. Note that the chip notch position is installed facing the circuit board notch mark.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e Product parameters:PCB diameter:50mm; input voltage:3-6v;Required tools: electric iron: 30W, solder wire: 0.8mm, tweezers, oblique pliers, multimeter.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e Suitable for electronic DIY electronic hobby beginners to learn and practice welding.It is widely used in schools to help students learn basic mechanical and electronic skills.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003c\/span\u003e\u003c\/div\u003e","brand":"mickcara","offers":[{"title":"000","offer_id":41131062755465,"sku":"00045-1","price":19.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0365\/2131\/2393\/products\/a9070e87746bdf31ecd4f2ab6c04d922.jpg?v=1675751318","url":"https:\/\/mickcara.com\/products\/diy-electronic-kit-set-electronic-lucky-turntable-water-lamp-lottery-diy-assembly-small-production-competition-welding-practice","provider":"mickcara","version":"1.0","type":"link"}
