C1 and charge again this cycle oscillations formed . Charging time : 0.695 (R2 + R3 + R4) C1, discharge time : 0.695 (R4 + R3) C1, R4 can be adjusted to control the output frequency of the oscillator , the oscillation clock signal is applied continuously NE555 CD4017 14 feet , the output terminal 10 is connected with the CD4017 10 LED, when the output terminal 10 turns CD4017 generated clock signal is applied at a high level , the D1 - D10 are sequentially lit to form a water -light effect . You can adjust the flow rate adjustment R4 LED lights . Package included: 1* NE555+CD4017 Flow LED Light Electronic Production Suite.1  NE555+CD4017 Flow LED Light Electronic Production Suite. PCB board size: 7.3 3.2mm. PCB thickness: 1.6mm.\u003c\/p\u003e","brand":"Shop2IndiaBei","offers":[{"title":"Default Title","offer_id":43031366107304,"sku":"U2I-1-401968834864","price":1280.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0300\/1588\/1354\/products\/s-l2000__99962_e50858b2-4042-4c76-bc63-3a8039c0c9e2.jpg?v=1672577753","url":"https:\/\/shop2india.com\/products\/led-chaser-flowing-water-light-ne555-module-cd4017-pcb-board-diy-kme","provider":"SHOP2INDIA GATEWAY","version":"1.0","type":"link"}
