What is LED chaser used for?
A light chaser serves as an LED driving circuit. It contains an arrangement of LEDs set in a certain pattern to provide a chasing light effect. For example, the LED chaser circuit creates the flashing light effect in a disco.
How do you make a LED chaser?

How does a LED chaser circuit work?
This is the circuit of a simple LED chaser. The LEDs lights one by one for a period of 1second and the cycle repeats giving the running light appearance. The circuit uses two ICs (one is 555) to drive the LEDs. IC1 (NE555) is the popular timer IC wired in the Astable Multivibrator mode.
What is the use of IC 4017?
CD4017 is used for low range counting applications. It can count from 0 to 10 (the decade count). The circuit designed by using this ic will save board space and also time required to design the circuit. CD4017 is as ‘Johnson 10 stage decade counter’.
What are the disadvantages of LED lamps?
What are the disadvantages of LEDs?
- High up-front costs.
- Transformer compatibility.
- Potential color shift over lamp life.
- Performance standardization has not yet been streamlined.
- Overheating can cause reduced lamp life.
What is LED sequencer?
The so-called chaser or sequencer is one of the most popular types of LED-driving circuit and is widely used in advertising displays and in running-light ‘rope’ displays in small discos, etc.
How does a 4017 chip work?
Whenever a clock pulse is received at the clock input of the IC 4017 counter, the counter increments the count and activates the corresponding output PIN. When the count is zero, PIN-3 is HIGH, which means LED-1 will be ON and all the other LEDs are OFF.
How many output pins are present in 4017 IC decade counter?
When this pin is high the 4017 will not advance to the next out put but the reset pin is still active. The 4017 has 11 outputs. There are the regular 10 outputs and a carry out that outputs a pulse when 10 is the current high output and a pulse on the clock pin is received.
How do you make an LED chaser with Arduino?

What is the lifespan of LEDs?
According to lighting experts, LEDs are sustainable, eco-friendly, efficient, and safe lighting solutions that deliver multiple benefits to the users. In addition, LED lights are known to last longer and typically enjoy a lifespan of almost 50,000 hours.
How does a 4017 work?
What is the use of 4017 IC?
How does 4017 IC Blink the LEDs in sequence?
Then 4017 IC will blink the LEDs in sequence as per the signal in the clock pin (14). This the schematic of the 10 LED chaser with only 4017 IC.
Where can I get the Gerber file for 4017 PCB design?
But you can also download the PCB Gerber file for this 4017 project, and order the custom design PCB from PCBWay.com PCBWay not only produce FR-4 and Aluminum boards, but also advanced PCB like Rogers, HDI, Flexible and Rigid-Flex boards, with very reasonable price.
How to make simple led chaser circuit using cd4017 IC?
To make this simple LED chaser circuit I have used only a 4017 IC. Here the flashing RGB LED will generate the clock pulse for CD4017 IC. Then 4017 IC will blink the LEDs in sequence as per the signal in the clock pin (14).
