NE555 CD4017 LED Lucky Turntable DIY Electronic Soldering Kit – 3V

Build your own electronic lucky turntable with this hands-on DIY soldering kit! Powered by the classic NE555 timer IC and CD4017 decade counter, this 3V circuit kit lights up 10 LEDs in sequence around a circle. Press the button, watch the LEDs chase and gradually slow down — then see which one lights up last. A perfect introduction to practical circuit assembly, soldering skills, and fundamental electronics concepts.

Please note: This kit is designed for electronics enthusiasts with basic soldering and circuit experience. All components are quality-checked before shipment; however, successful assembly depends on the builder's skill level. Please read all instructions carefully before beginning.

How It Works

When the push button is pressed, the 10 LEDs illuminate one after another in a rotating sequence. The cycling speed gradually decreases until the light stops on a single LED — just like a spinning lucky wheel or electronic dice. It can be used as a number-guessing game, a random selector, or simply as a fun circuit-building project.

Frequently Asked Questions

Q: Is this NE555 CD4017 LED turntable kit suitable for beginners?

A: This kit is best suited for individuals with some prior soldering and electronics experience. While it's a great learning project, basic familiarity with reading circuit diagrams and handling a soldering iron is recommended for successful assembly. Beginners should proceed carefully and follow instructions closely.

Q: What power source does the LED lucky turntable kit require?

A: The kit operates on a 3V DC power supply. This can typically be provided by two AA or AAA batteries in series. A power source is not included in the kit — you will need to supply your own 3V DC power.

Q: What are the main uses for this DIY electronic turntable kit?

A: Once assembled, the kit functions as an electronic lucky wheel, random number selector, or electronic dice simulator. It's also widely used as a soldering practice project, teaching aid for NE555 and CD4017 IC circuits, and a fun STEM demonstration tool for classrooms or workshops.

Q: Are all components included in the kit?

A: Yes, the kit includes all the electronic components needed to assemble the circuit board, including the NE555 and CD4017 ICs, 10 LEDs, resistors, capacitors, PCB, and other through-hole parts. A soldering iron, solder wire, and power supply are not included and must be sourced separately.
