This circuit is also called as “LED chaser circuit”. The LED sequencer circuit by using IC 4017 and IC 555 is shown below. Application of IC 4017 LED Sequencer using 4017 Next this output is shifted to its next output pin and this sequence continues till the next clock cycle. Then the output of the first output pin 3 will be high. If we observe that, before applying the clock signal, the RESET is set to High, so the reset pin input sets all the output to their initial state. This is the timing diagram of the IC 4017 with, shows us the comparison and also explains the counting sequence of the outputs, shifting from one pin to its next. Counting operation of IC 4017 using waveforms This is used to ‘ripple’ the IC, which means to delay in counting operations.

It completes one full cycle for every 10 clock cycles. The pin 12 is supplied with the CARRY OUT signal. Pin number 8 acts as ground and it must connected to negative supply voltage & pin number 16 is the supply pin for IC 4017 and it is connected to positive voltage supply. To operate the IC correctly, the pin 15 must always connected to ground. This resets the output only to the positive supply voltage so if we apply a positive voltage at pin number 14, the output sequence starts freshly at pin 3. This reset the sequence of the output to the initial state. The 15th pin of IC 4017 is acts as RESET pin input. The clock input pin (pin number 14) responds only to the positive voltage signal or positive clock and the order of outputs, when we apply clock signal is 3, 2, 4, 7, 10, 1, 5, 6, 9, and 11. It must not leave unconnected as per the CMOS input standard rules. The important thing to remember is, if we don’t connect any clock signal to this input pin, it must be connected to either positive or negative voltage supply. In IC 4017, the clock signal is applied to the pin 14.

The above explained sequencing of the output from one pin to another will happen only when the clock signal is applied to the IC. But this pin must be connected to the ground to enable the functioning of the IC. Instead of this, the 14th pin is supplied with standard clock signal to the IC. Generally this pin is not used for applying the clock signals. The pin number 13 will respond to negative peak of clock signal. So the phrase “output pins changes to high” means ‘the output produces a positive voltage in a sequential manner, from one output to its next output pin’. Here high means ‘positive voltage’ which may be equal to the source voltage or supply voltage to the integrated circuit (IC chip). This will continue till the last output pin 11 becomes high and again it starts at pin 3 (the cycle repeats). Thereafter the second output pin 2 becomes low and third output pin 4 becomes high. For example, we know that the first output pin is 3, then it becomes low and simultaneously the next output pin 2 will become high. The output pins changes to ‘high’ level one by one (one after another) in a sequence. Generally the IC 4017 is called as ‘Johnson 10 stage decade counter’. This IC is most useful for the numerous electronics applications. The IC 4017 is simply designed for counting the pulses and clock signal. Th circuit designed by using 4017 IC will save board space and time required to design the circuit.

It can count from 0 to 10 (the decade count). This is a CMOS decade counter, which is used for low range counting applications.
