How does IC 4017 work?
IC 4017 is a digital counter plus decoder circuit. The clock pulses generated at the output of the IC 555 timer (PIN-3) are given as an input to IC 4017 through PIN-14. After the next clock pulse, PIN-2 of IC 4017 is HIGH, which means that LED-2 will glow and all the other LEDs can be turned OFF.
What are the internal components for the 4017 IC?

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.
What is the function of 555 timer IC?
The 555 timer IC is an integrated circuit (chip) used in a variety of timer, delay, pulse generation, and oscillator applications. Derivatives provide two (556) or four (558) timing circuits in one package. It was commercialized in 1972 by Signetics.
What is IC pinout?
The pins on an IC chip provide connections to the tiny integrated circuits inside of your electronics. So, for example, with the clocking notch orienting the chip at the 12 o’clock position, the pins of a 14-pin IC are numbered 1 through 7 down the left side and 8 through 14 up the right side.
What is the internal structure of the IC 4017?
The ic 4017 internal structure is shown below. It has 16 pins and the functionality of each pin is explained as follows: Pin-1: It is the output 5. It goes high when the counter reads 5 counts. Pin-2: It is the output 1. It goes high when the counter reads 0 counts. Pin-3: It is the output 0.
What kind of circuit can I do with IC 4017?
Often use IC 4017 CMOS-IC. This really neat chip contains a counter and a decoder circuit, that can show a single output pin for each count from 0 to 9. Do not just look at it. You should learn with doing many circuits using 4017.
How many pins are in an IC 4017 decade counter?
Pin Configuration of IC 4017 A CMOS decade counter like 4017 IC includes a five-stage Johnson counter & 10 decoded outputs for counting up to 10 decimals. This IC can be used in different counter circuits such as an LED chaser light & also a non-contact circuit with an AC detector. This IC includes 16-pins where 10 & 16 pins are output pins.
How does the 4017 IC work on a flasher?
By default, the first output pin is on/high and the rest are off. Each time the clock input pin of 4017 IC detects a rise in voltage (from low to high), it turns off the current output and turns on the next sequential output.
