This series consists of 10 led a mounted sequential, Supply 9V IC1A needed to strengthen to 100 times and move the audio signal IC1B. Sensitivity level of the circuit can be adjusted by changing the value of R4. The value of C4 was changed from 220 to 470nF. Each input R9 must be linked with the IC2 output pins.

IC Decoder 4017
The 4017 is an extremely useful device for project work and is used in the Games Timer and in various DOCTRONICS construction kits including the Light Chaser and the Matrix Die. When you are familiar with the 4017, you will be able to think of lots of useful applications.
Internally, the 4017 contains five bistable subunits. These are interconnected in a pattern known as a Johnson counter. The outputs of the bistables are decoded to give the ten individvual outputs.
