This is a basic LED chaser or LED running light. It can be used as a decorative light, fancy light, chasing taillight for vehicles, etc. The circuit consists of the famous Timer IC 555 astable multivibrator and the 4017 counter acting as the LED Driver. The output of the 555 generates a square wave or clock input for the decade counter. For each positive edge of the clock input, the counter shifts the high state of the output in a sequence from output 0 to output 9. Since only one output will be high at a time and the remaining outputs will be in the low state. The shifting cycle repeats like a ring counter. Thus the LEDs will visually seem like a rotating.
