Running Light Chaser Circuit - Electronic Project

Introduction:

What is LED Chaser Circuit: The LED Chaser Circuit is an electronics circuit where the LED lights glow one by one for a period of time and the cycle repeats giving the running light appearance. You probably saw the various types of adornment lighting patterns in fair, some of the LED Light patterns are built based on the LED Chaser Circuit. Basically, a Simple LED Chaser Circuit is made of 555 Timer IC and CD4017 counter IC. Using this circuit we can build different types of home decoration products and Running LED light displays.

You may have seen LED lights in different events for decoration and other ideas. Therefore, there are many different current kinds of LED circuit diagrams available in the power supply market. One of them is the LED chaser circuit. In the chaser circuit diagram, LEDs glow or blink 1 after another. In other words, you can say that 1 LED chases the Circuit diagram next LED. Hence named the chaser circuit. To understand the circuit and its working.

In this tutorial, we are going to “Running light chaser circuit” The circuit uses two ICs including a 555 timer IC which generates the oscillation, and a counter CD4017 IC. Thus, the circuit is simple to make, requires fewer external components, and hence affordable for students to begin their learning about electronic devices and circuits.

Working Principle of LED Chaser Circuit and Project:

The main part of this Circuit diagram LED chaser circuit diagram is the power supply most popular timer IC NE555 which project system generates some variable frequency. The 555 timer IC can be power supply configured in some different modes like Astable, project system Monostable, and Bistable, in this project system, we configured it as an Astable multivibrator in which both the circuit diagram stages of the signal are unstable. Sometimes this power supply configuration is also known as a Could frequency generator.

Resistors R1, Potentiometer VR1, and capacitor C1 act as the timing components and we can change the output frequency cycle of 555 timer IC by adjusting the Potentiometer VR1. By changing the output frequency we can change the switching speed of the LEDs. The output pulses are available from the output pin 3 of 555 IC.

lC1 (NE555) is the popular timer IC wired in the Circuit Diagram Astable and Multivibrator mode. Resistors R1, as VR1, and capacitor C1 act as the power supply timing components and the power supply output pulses are available from the Circuit diagram output pin 3 of IC1. These pulses are given to the project system input pin 14 of the Johnson decade power supply counter IC CD4017. Out of the 10 outputs of the power supply IC2, as eight outputs are used to drive the current LEDs.

The ninth output pin 9 is connected to the Circuit diagram reset pin 15 to stop the power supply counting. So that the cycle repeats. With the value of C1, each LED remains on for 1 second. When 1 LED turns off, the project system the second 1 turns on. This cycle repeats giving the running light power supply appearance. Resistor R3 keeps the project system input pin 14 of IC2 low after each pulse.

This circuit diagram configuration is almost the same as the above circuit diagram, the only difference is in the project system knight rider circuit the sequencing of and on the LED is arranged with diodes to obtain a power supply to-and-fro motion of light. The output from 0 to 5 is connected as a power supply same as in the above chaser circuit diagram, but from output 6 onwards it is connected in a power supply reverse sequence. Thus the LED lights one by one and moves forward, once the 6th LED is reached the direction reverses and moves towards output 0. This movement repeats like a swing action.

Frequently Asked Questions

Do LEDs need AC or DC?

Because LEDs use semiconductors, as they require a low-voltage DC Circuit diagram (direct current) power supply to operate, and cannot be powered supply directly by AC (alternating and current) power supply like an incandescent bulb can.

Can LED glow with AC?

LEDs consume DC current to produce light; as with AC current, the Circuit diagram LED will only be lit when the current flow is in the power supply's proper direction. AC applied to a project system LED will cause it to blink on and off and on, and at high frequency, as the LED will appear to be lit power supply continuously.

What is LED chaser Arduino?

An LED chaser or sequencer is a power supply popular LED driving circuit diagram. It's used in running-light rope displays to flash power supply different lighting patterns. In a power supply chaser or sequencer circuit diagram, a controller commands the power supply sequence and timing of the project system flashing LEDs to illuminate different kinds of the power supply lighting patterns.

Can LEDs convert AC to DC?

In conclusion, LED lights can be powered supply using both AC and DC power supply sources. LED drivers or transformers are project systems typically used to convert the high-voltage AC power supply to low-voltage DC power that is safe for the Circuit diagram LED lights to use.
