2/11/2023 0 Comments Ic 4017 working principle download![]() For a detailed explanation regarding IC 555 astable, you can click on this articleĪs can be seen in this configuration, in response to the pulses from IC 555, the IC 4017 generates a running or chasing light pattern across the connected 10 output LEDs.For learning the pinouts and datasheet of the IC 4017 please refer to this article. ![]() LEDs RED, 5mm High Bright or as desired = 11nos.Simple LED Chaser Circuit Diagram (The 100K pot can be adjusted to get any desired chasing speed or rate)Īll resistors are 1/4 watt 5% unless specified This design requires very few components for the configuration. Though the more complex lighting might need the incorporation of microcontroller ICs, simpler yet very interesting light effects can be generated through ordinary ICs like IC 4017 and IC 555 as shown below. These look very interesting and are surely eye catching and that’s why these types of lighting arrangement have gained immense popularity in today’s world. Light chasers are decorative lights or LEDs arranged in different moving patterns which create a chasing light or running light kind of effect. The proposed circuit is transformerless and is thus a lot compact and light weight. These primarily incorporate LEDs as well as mains operated bulbs through triacs. We also discuss how to modify these into a design popularly known as "knight rider" chaser circuit. ![]()
