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 L\u003c\/p\u003e\u003cp\u003eFree shipping included. 30-day hassle-free returns.\u003c\/p\u003e","brand":"Belmont Warehouse","offers":[{"title":"Default Title","offer_id":43359011537105,"sku":"BW-B07VP4664X","price":17.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/3123\/5793\/files\/61HsbyCwbIL._AC_SL1500.jpg?v=1790997212","url":"https:\/\/belmontwarehouse.com\/products\/devmo-ne555-cd4017-running-led-flow-led-light-electronic-production-suite-control-board-module-capacitor-oscillator-clock-siganal-diy-kit-diy-kit","provider":"Belmont Warehouse","version":"1.0","type":"link"}
