Product description
Are you looking for the perfect project to practise soldering, a fun e-experiment for long evenings, or an original light-up decoration that reacts to music and speech? This DIY kit for a colourful rotating LED effect, featuring the CD4017 integrated circuit, is the ideal choice for budding hobbyists, electronics students and advanced DIY enthusiasts who love visual audio effects.
This interactive electronic kit uses a sensitive microphone to pick up ambient sound. As soon as you speak, clap or play music, the colourful LEDs arranged in a circle immediately start flashing, creating a dynamic rotating light effect. The speed and intensity of the rotation vary precisely in time with the rhythm and volume of the sound.
Key features you’ll enjoy:
- A great introduction to soldering (educational DIY kit): The printed circuit board is laid out very clearly. Assembling this kit will guide you through the basics of fitting classic (THT) components, from resistors to integrated circuits.
- Acoustic control (Voice Control): No boring buttons. The circuit responds to clapping, music, your voice or any other sound stimulus thanks to a sensitive electret microphone.
- Legendary architecture featuring the CD4017 and NE555: At the heart of the effect are two of the most popular chips in the world of electronics – the NE555 timer, which acts as a clock pulse generator, and the CD4017 decoder, which ensures the LEDs are switched on sequentially in a circle.
- A colourful light show: Once completed, the combination of high-brightness coloured LEDs creates a spectacular visual display that will perfectly adorn a desk, a child’s bedroom or a model-making project.
Technical specifications (All data in one place)
- To ensure trouble-free assembly and safe operation, we provide the complete technical specifications of the kit:
- Product type: Electronic DIY kit (Do-It-Yourself assembly kit)
- Main integrated circuits: CD4017 (decimal counter/decoder) + NE555 (universal timer)
- Sensor type: Electret microphone with adjustable transistor gain
- Supply voltage: 4.5 V to 12 V DC (can be powered from a battery pack, power bank or mains adapter)
- Component mounting type: THT (traditional through-hole components for easy hand soldering)
- Light source: High-brightness coloured LEDs (arranged in a circular pattern)
- Printed circuit board dimensions: Compact circular/square format, ideal for installation in enclosures
Package contents:
- 1× printed circuit board (PCB) with clear markings for component placement
- Set of coloured LEDs
- CD4017 and NE555 driver ICs (including protective sockets for easy assembly without the risk of overheating the chip during soldering)
- Electret microphone, capacitors, resistors and control transistor
Experience the magic of electronics for yourself, or give a young tech enthusiast a gift that will really teach them something. Add the DIY voice kit with the CD4017 to your basket and experience the joy of building a working device with your own hands!
