This is running LEDs circuit which use timer ID NE555N and logic IC 4017N. IC 555 act as a multivibrator and generate frequency to be used for 4017 clock input.
The 4017 is a high speed silicon gate CMOS 5-stage Johnson counter with 10 decoded outputs. Each of the decoded outputs is normally low and sequentially goes high on the low to high transition clock period of the 10 clock period cycle. The CARRY (TC) output transitions low to high after OUTPUT 10 goes from high to low, and can be used in conjunction with the CLOCK ENABLE (CE) to cascade several stages. The CLOCK ENABLE input disables counting when in the high state. A RESET (MR) input is also provided which when taken high sets all the decoded outputs, except “0”, low.
R2 is a linear potensiometer to adjust clock frequency and of course the frequency of the blinking LEDs as well.

hi,. i would like to do this project,. i want to know what are the materials needed? thanks.,
i have a running light project too...but mine is just simple...im kinda disappointed to have found out about your site after i finished my project...i could have done better...anyway,where is this applied?
what are the materials for that circuit
diagram???
becausei?m doing that in my project?
what are the components required for this........
