what is the function of ic 4017 in clapswitch?
4017 IC is a counter, divider integrated circuit. It is a decade counter that has 10 different decode outputs and is commonly called a CMOS.
just conect gnd to the vcc
working
Depending on the package type and where you buy it, one 4017 costs somewhere between $0.30 and $1.00 US.
The IC 4017 works as a digital counter and decoding unit. The circuit can count from 0 to 10 and has 16 prongs with LEDs that light up as each prong is being utilized.
go to datasheetlocator.com and find it yourself.

4017 is a decade counter having 10 output pins with different functions. When a source of pulses is connected to the clock input by unstable circuit of any timer IC applied to the reset and disable input. One of the individual output is high at a time. thanx......

There are many ways you can design a simple traffic light circuit. I recommend you to use a 4017 IC. Please check this site as reference. It's a two way traffic light circuit. http://circuitdesolator.blogspot.com/2011/01/traffic-light-circuit-based-on-4017.html
The two most likely reasons are:you want to count in decimal for a human readable displayyou want to divide the pulse rate of a signal by multiples of ten (i.e. a decade)
IC's which starts from 7 are most of them are digital ic's . not all the IC's starts with 7 for example LM380 audio IC CTC810 audio amplifier ic and lm317 voltage regulator ic ,NE555 timer ic, 4017 counter and so other. there are no fact behind them . 7400- nand 7402 -nor 7404-not 7408-and 7432-or 7486-exor 74266-ex-nor 74147 priority encoder.
