CD4017 = CMOS decade counter with 10 decoded outputs

CD4017 is most used from CMOS 4000 series, because can be used in many applications (hobby, diy, industrial, etc).

First, you must study datasheet of this integrated circuit, when you will see pinout for CD4017:

and timing diagram is

Ok, because is more easy to understund by practice, I put here my base test schematic designed in an old version of Eagle PCB software.

You can made on PCB board:

(Board file in pdf format can be download from HERE !)

   For 10 outputs, must connect this schematic:

You can made on PCB board:

(Board file in pdf format can be download from HERE !)

   For use you must connect first module with second module:

    I made a simulation using Live Wire software and I put 10LEDS drived by CD4017 movie on my youtube channel:

   I f you want to made “knight rider” you have next situations:

You must change second module with this:

(Board file in pdf format can be download from HERE !)

        I made a new simulation and I put 5LEDs drived by CD4017 (knight rider)
