2032-SA2 - CD4017 COLORFUL VOICE CONTROL ROTATING LED LIGHT KIT

^{Colorful voice controlled rotating LED light DIY soldering kit based on CD4017 chip.}

Circuit board: 1.6mm thick 48mm diameter

Supply voltage: 5V DC voltage.

Function Introduction:

The CD4017 IC is a decade counter that counts to ten. It has 10 outputs that represent the numbers 0 to 9. The counter increases with one for every rising clock pulse. After the counter has reached 9 it starts again from 0 with the next clock pulse.

This is a great chip for making running LEDs!

The circuit of this set adopts sound control to run 10 LEDs in rotary  format.
