IC CD4017 is a CMOS decade counter IC. It can produce output at the 10 pins sequentially, i.e. it produce output one by one at the 10 output pins. Explore below some interesting electronic circuits based on IC CD4017.
LEDs are commonly used in electronic circuits, and with the LEDs, you can make many things which are interesting. You’ve probably seen many types of decorative lighting patterns-running lights, festival chasers, or rhythmic blinking effects that instantly stand out. This LED chaser circuit recreates that eye-catching style using a simple combination of the 555 timer…
Frequency Dividers are the circuits which divide the input frequency by n (any integer number), means if we provide some signal of frequency ‘f’ then the output will be the divided frequency ‘f/n’. Frequency dividers are very useful in analog as well as digital applications. Here we are building the circuit to divide the frequency by 2 or 4.

Have you ever feel a shock by touching the switch? It does not generally happen but sometimes physical contact with switches may be dangerous. But what if the switch gets wireless and you don’t have to press any button at all for switching on or off your home appliances. So today we are building a Simple Wireless Switch Circuit in which there is no need of physical contact…
In this project, we are going to Control the Speed of Dc Motor Wirelessly Using IR or TV Remote Control. Here we are not going to use any microcontroller. We have used basic components along with 555 Timer IC to complete this task. This circuit can control the DC motor speed in 5 different levels and any IR remote like TV/DVD remote etc can be used to control it.

Toggle switch is used to toggle the output between two devices. Means when one device is ON, second device remains OFF and when second device is OFF, first device becomes ON. This toggle of output can be controlled using a PUSH button switch, so you can control two devices using one button. Further you can interface two Relays in place of LEDs to control the two AC…
Dice can be used to play several games, such as Snakes and Ladders, Ludo, etc. Generally, dice are made of wood or plastic, which gets distorted over time and becomes biased. A digital dice circuit is an alternative to the traditional dice; it can’t be biased or distorted, and it acts so fast that nobody would be able to cheat.
This guide will explain how to build a digital dice circuit…
A decimal counter is a chip designed to count the number of pulses or events that occur in digital circuits. These chips show the output in the decimal form or 1 to 99... form. So if we have a 12 bit counter, then it can count only 12 clock pulses or 12 events. These chips memorize the events and show the count of events at output port. The chip memorizes the event and shows…
Dancing LEDs circuit is used for decorative purpose and looks very good when these LEDs glow in sequential manner. We can create many kind of Dancing LEDs patterns for decoration. In this particular circuit, we have created a pattern in which 6 LEDs are illuminating in forward and reverse order. To create this circuit we have mainly used 555 timer IC and 4017 IC.

You must have seen different kinds of decoration lighting patterns. In this LED chaser circuit, we have created an interesting LED blinking pattern by using a 555 timer IC and Counter IC CD 4017.
Required Components CD 4017 Counter 555 Timer IC 150, 1K, 10K Resistors 10K Variable Resistor 10uf, 100nF capacitor…
Electronic clock with LED pendulum & tick tock sound produces Tick Tock sound every second and it has a LED pendulum in which 6 LED glow in forward and reverse sequence like a Pendulum, each LED glow in one second. This circuit is very useful and inexpensive. You can build your own clock which can be used in many applications like toys, robots etc. To create…
In this tutorial we are going to build a Heart shaped serial LED flasher circuit using 555 timer IC and 4017 IC. It is an interesting DIY which you can build for yourself or gift someone special to you.
Required Components
555 Timer IC
Decade Counter IC 4017
Resistors - 220 Ohm, 1k and 10k
Capacitor - 10µF…
In this project we are going to design a circuit, to make a flashing light similar to that on a police car. This police light circuit is designed by 555 Timer IC and a decade counter IC. The timer here generates pulses which are fed to the 10-stage decade counter, the output of counter is so arranged to get a flashy lights as a police car.
