The NE555 + CD4017 Water Flowing Light LED Module DIY Kit is a classic electronics learning project that demonstrates LED sequencing using timer and counter ICs. The circuit uses the NE555 timer to generate clock pulses, which are then fed into the CD4017 decade counter IC to produce sequential output across multiple LEDs.
This creates a visible Water flow lighting effect, making it easier to understand how timing signals control digital outputs. The Water flowing Module is designed on a compact PCB with pre-defined component positions, allowing straightforward assembly for learners.
This project helps users understand concepts like pulse generation, frequency control, and sequential logic circuits and make Decorative projects. It can be powered using a wide DC input range, making it compatible with basic power supplies and breadboard setups.
Available from StemVolt, this kit is ideal for students, hobbyists, and beginners exploring NE555 + CD4017 Water Flowing for student level projects and practical electronics learning.
