220 V AC LED Chaser Circuit
Table of Contents
Light Chaser is a circuit where 1 LED light is switched on after another LED. That’s mean Leds are chasing each other. This is Very easy 220 V AC LED Chaser Circuit Diagram.
This 3 Channel Light Chaser Circuit is mainly made of 2 ICs, 555 timer IC & 4017 Counter IC. Using these components we can decorate with forward & reverse wave only.
You can modify this circuit from 3 Channel to 10 Channel its very easy i will explain every thing to you in this ( 220 V AC LED Chaser Circuit Diagram) Article.
220 V AC LED Chaser Circuit Diagram
The 3 Channel Light Chaser Circuit works with two ICs, 4017 & 555. The 555 Timer IC sends a clock pulse to the 4017 Counter IC. The counter IC counts and sends a signal to the next output pins. There are a total of 16 pins in the 4017 IC. out of them, 10 pins are output pins. When it completes 10 counting’s, it again counts from 1st pin

220 V AC LED Chaser Circuit Diagram Working
This Circuit is based on Timer IC555 & IC4017. The 555 Timer IC sends a clock pulse to the 4017 Counter IC. The counter IC counts and sends a signal to the next output pins. There are a total of 16 pins in the 4017 IC. out of them, 10 pins are output pins (Output Pin No. 3,2,4,7,10,1,5,6,9,11) and pin no 15 is Reset pin. When it completes 10 counting’s, it again counts from 1st pin.
But in this circuit we are using only 3 output pins Pin no 3,2 and 4 and reset the 4th output pin no 7 with IC Reset Pin (Pin No. 15).With same method you can use output pins as per your need. Example if you need 6 channel chaser you can use pin no 3,2,4,7,10,1 as output pins and reset pin no 5 with pin no 15. You can make 3-10 output led chaser lights as per your need just changing the reset pin connection.
IC 555 & IC4017 Pinout
This Touch Switch Circuit Diagram is built around a 555 timer by making use of the default properties of the Pins of the 555 Timer IC. With the help of this circuit, you can turn ON and OFF a device by simply touching the……. Read More
How LED Chaser Lights Works With 220 Volt AC
Here we are using 12 volt Relay for this purpose you can see in circuit diagram. Use relay according to your need Because AC Load is depends on Relay amperes
