LED knight rider circuits utilize on a car, bikes, bicycles, trucks, buses, and so on as they give eye-capturing impact to the viewers.
It can likewise be utilized as a piece of decoration at numerous places like home, parties, and so forth.
Right now, in this project tutorial, we will demonstrate to you to make an eye-capturing and amazing circuit. An 11 LED knight rider circuit. That can pursue 11 LEDs in a forward-reverse pattern. They streak one at a time while pursuing one another.
In this circuit, we utilize a 555 IC as an astable multivibrator to deliver positive pulses. While two CD4017 Johnson decade counter is coordinated with 555 IC to enact LEDs one by one.

Circuit Diagram
Circuit Operation
This simple 11 LED knight rider circuit is utilizing two different ICs. IC1 is a 555 clock that is operating as a positive pulse generator. IC2 and IC3 are CD4017-decade counter ICs which enact LEDs individually when it gets positive pulses on its clock input pin 14. In the above circuit diagram, 4017 ICs are integrated in a cascade pattern.
All the power diodes utilize in this circuit are general 1N4148 diodes. The working voltage of the circuit is 5V to 12V DC. In the event that you need to work the circuit from 5V or 6V, at that point utilize a lower-value resistor like 220 ohms or 240 ohms in place of 390 ohms, to make the LEDs shine more brilliantly. The sequencing velocity can be balanced with the 100K variable resistor which is connecting in the circuit.
Applications and Uses
Regular uses of knight rider LEDs are:
- They can be used as home decorators, parties, and special occasion lighting.
- Automobile lovers are utilizing these lights in upgrading the lighting effects of their transports like cars, motorcycles, cycles, trucks, buses, etc.
- These Knight riders are additionally used in the frequency alteration of various instruments.
