Pada saat baterai dipasang, pin 14 IC 4017 di trigger oleh output pin 3 dari IC NE555 sehingga arus mengalir pada masing-masing LED secara bergantian sesuai urutan output pada IC 4017. Rangkaian ini memanfaatkan IC 4017 sebagai driver LED dan IC NE555 sebagai timer nya. I have a well enough experience in website blogging and technical content writing.Īplikasi running LED ini dapat dipasang sebagai aksesoris pada motor atau sebagai hiasan dan ornamen yang membutuhkan animasi cahaya yang menarik. It can also be used outside shop windows, home decorations, parties and other special occasions. The pulse frequency or the speed of the running LED expands or diminishes with the 100K variable resistor.įor instance, in the event that you are working the circuit with less than 9V, at that point utilize 290 ohms resistor. In the circuit the yield outputs of the ICs are associated in a way so it will show turn around forward running the LEDs. The IC will initiate every one of its output in a succession way when each time a positive pulse gets on its clock input pin 14. ![]() For instance, it gives an electronic pendulum impact to a digital clock, or it very well may utilize as a warning indicator.
