These circuits can be employed on a car, motor cycle, bike etc. In this, the LEDs simply turn on one after the other in a sequential fashion. The third circuit is also implemented using CD

LED Chaser using 4017

The blinking sequence is marked with numbers on the LEDs. You can also use transistors at each output to drive more LEDs on each output. The circuit can also be used for many other pulse generator purposes. The circuit is using 3 ICs. The timer IC with photocoupler is used to provide positive pulses to both the ICs one by one. The speed of the pulses or chasing speed can be increase or decrease with the K variable resistor. The circuit can be operated with 5V to 12V DC.

LED CHASER With IC555 and IC4017

You must have seen different kinds of decoration lighting patterns. When we power the circuit, LEDs start glowing one by one for a defined time period. So that counter changes its state faster. Here in this project we configured timer as an Astable multivibrator in which both the stages of signal are unstable. Some time we call frequency generator also. MR pin pin 15 , enable or clock inhbit pin pin 13 is directly connected with ground and Clock pin of counter directly connected with output pin of Timer.

The article discusses the construction of 9 interesting LED chaser circuits, which not only create beautiful running light effect but are also easy to build. We also discuss how to modify these into a design popularly known as "knight rider" chaser circuit. These primarily incorporate LEDs as well as mains operated bulbs through triacs. The proposed circuit is transformerless and is thus a lot compact and light weight. Light chasers are decorative lights or LEDs arranged in different moving patterns which create a chasing light or running light kind of effect. 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 and IC as shown below.

The circuit is useful for applications like running light systems in halls, decorations, dance programmes, counting and so on. The 9V battery power supply is stepped down to 5V using a voltage regulator along with two 0. IC2 is wired in astable multivibrator mode. Frequency f can be calculated using the relationship:.

If you would like to learn basic digital, but it is difficult and boring. It used in computer games and in many scientific and mathematics applications so is best for a beginner or for kids to learn digital, also my son loves them. The working principle. See in the circuit above. Which the output pulse frequency at pin 3 of IC1 is determined by R1, R

Here we are going to make LED chaser. LED chaser circuit mainly consists of two circuits. The IC circuit is mainly used for providing free running frequency output. IC is a 16 pin out ic. IC mainly consists of two internal blocks. The decoder converts the binary number to decimal number.

It consists — in essence — of a clocked IC or other electronic unit that drives an array of LEDs in such a way that individual LEDs or small groups of LEDs turn on and off in a predetermined and repeating sequence, thus producing a visually attractive display in which one or more ripples of light seem to repeatedly run through a chain or around a ring of LEDs. This article looks at a variety of practical circuits based on this particular IC. If desired, various outputs can be coupled back to the IC control terminals to make the device count to or divide by any number from two to nine and then either stop or re-start another counting cycle. Numbers of B ICs can be cascaded to give either multi-decade division or to make counters with any desired number of decoded outputs. The B is thus an exceptionally versatile device that can easily be used to chase or sequence a basic LED display of virtually any desired length. Nine of the 10 decoded outputs are low, with the remaining output high, at any given time.
