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.
How do I reset my IC 4017?
If you want to glow only 5 leds in a sequence instead of 10,connect the pin 1 of the 4017 to its reset. Thus when 6th clock pulse arrives, reset button goes from high to low transition and resets the IC.
What is led chaser circuit?
This is the circuit of a simple LED chaser. The LEDs lights one by one for a period of 1second and the cycle repeats giving the running light appearance. The circuit uses two ICs (one is 555) to drive the LEDs. When one LED turns off, the second on turns on. This cycle repeats giving the running light appearance.
Why IC 555 is called Timer?
The 555 Timer IC got its name from the three 5KΩ resistors that are used in its voltage divider network. This IC is useful for generating accurate time delays and oscillations.
How many IC 7490 will be required to count 99 events?
As we studied earlier, we can increase the counting capability of a Decade number by connecting more ICs n series; we can count 99 with two 7490 ICs connected in series. This 7490 IC has inbuilt Divide by 2 and Divide by 5 counters in it.
The IC 4017 is a versatile counter divider IC which can be applied for making many different interesting electronic circuits. In this post we will learn about a few useful yet simple 4017 IC circuits and projects, assorted and compiled from this blog.
