NE555 + CD4017 Red Blue Double Color Flashing Lights Board DIY Kit

The NE555 + CD4017 Red Blue Double Color Flashing Lights Board Kit is an engaging electronics project that combines the NE555 timer IC and the CD4017 counter/decoder to create a vibrant double-color flashing lights display. With red and blue LEDs, this kit offers a visually appealing light show. Ideal for DIY enthusiasts and electronics hobbyists, the kit provides an educational experience in assembling and understanding circuitry. The NE555’s timing precision and the CD4017’s sequencing capabilities make this kit an enjoyable and educational introduction to circuit building, offering a hands-on way to explore electronic components and their functions.

Features:

1. Interesting circuit for simulating the visual effects of warning lights, blue and red lights flash alternately according to the pulse respectively.
2.  The kit is simple to assemble, and suitable for electronics enthusiasts and students to practice.
3. Design optimized for training.
4. Red flashing lights and blue flashing lights are on separate boards and can move off from the stamp hole to increase the distance or separate installation to other places.
