This is yet another LED chaser circuit based on CD4017 and NE555. 

CD4017 and NE555 are very versatile chips. You can find hundreds of electronic experiments using these two chips on various sites. For example, check this out...

In this project, NE555 has been configured in astable mode and gives clock pulses at a set frequency to CD4017. Ten 5mm LEDs are connected to output pins of CD4017 and for each pulse from NE555, the CD4017 decade counter switches on its output pins to turn on the LEDs. 

The NE555 timer has been configured as a multivibrator using RP, R1 and C2

Adjust RP to adjust speed of chasing speed of the LEDs. 

Power supply: 4V - 12V DC

This project is suitable for electronics beginners who want to learn soldering and assembling electronic kits.
