LED Chaser by IC 4017 + IC 555

I believes in that extremely amateur electronics many you, may ever build the LED flasher or light blinks or the LED Chaser prevent come to already. Today I begs for to advise the circuit LED Chaser, by have LED show 10 amounts together. blink stick bright chase go to continually. By have IC 4017 precede at drive a tube LED all. Which its work be Counter circuit good just this besides. Still have IC 555 wait for feed Clock with then can fine the speed of the winking with VR1 good easy. The detail is other see in circuit picture better.
