Electronic Water Flowing Light DIY Kit, 555 Timer, FREE SHIPPING

  • $5.85


This DIY electronic water flowing light project operates from 3.0V-14.5V DC power supply.  It uses a 555 timer integrated circuit and decade counter CD4017 as its core components. The 555 timer is configured as a multivibrator where charging of C1 is configured using resistors R2, R3 and R4.  Read out how the 555 timer is configured here.

R4 resistance can be adjusted to control the frequency of the oscillator which will control the frequency of the blinking of the 10 LEDs. The LEDs D1 to D10 will be sequentially lighted to generate the water light flowing effect.

The electronic parts come in loose form and will have to be soldered to the printed circuit board that comes with this kit. The equivalent parts may be provided and different from shown in pictures.

Basic soldering and electronic knowledge are necessary to assemble this kit.
