This soldering project is about a DIY Electronic Clock kit with 18 LED Spectrum Effects. It automatically display the music spectrum when there is sound; Display the current time when there is no sound. Users can choose to switch between 18 music spectrum display modes and so on.

This is a really good intermediate kit, especially if you want to try a few surface mount components. This kit has a great variety of component mounting styles. It also has two ICs and a few capacitors that are surface mount to test your skills.

Features:

  • SMD SOLDERING KIT: DIY spectrum clock soldering kit primarily adopts a SMD design. Due to the small pin spacing of some components, assembly requires patience and soldering experience. The challenging assembly process not only provides the joy of DIY but also serves as an excellent opportunity to hone soldering skills.


  • SIX-DIGIT CLOCK: Features a six-digit display, providing enhanced accuracy in timekeeping. Additionally, it supports a switch between 12-hour and 24-hour formats, catering to your diverse preferences. Its minimalist design allows for seamless integration into various settings, making it a unique and stylish decoration for any occasion.


  • 18 SPECTRUM EFFECTS: Supports 18 spectrum effects and is equipped with a microphone module. When sound is detected, the clock automatically switches to spectrum mode, showcasing vibrant light effects. Once the sound stops, it seamlessly returns to normal clock display. You can personalize the transition time according to your preferences, turning the clock into not just a timekeeper but a perfect blend of music and visual spectacle.
