Build Your Own Rotating LED Digital Clock – A Fun DIY Electronics Project

The LOTHYE DIY Rotating LED Electronic Digital Clock Kit is the perfect hands-on project for electronics enthusiasts, students, makers, and hobbyists. Powered by the DS1302 real-time clock chip and a 51 SCM microcontroller (pre-programmed and ready to use), this kit lets you solder and assemble a fully functional digital clock with rotating LED animations, temperature display, alarm settings, and automatic light-controlled brightness — all from scratch.

⚠️ Please Note: This product is designed for individuals with circuit assembly experience. Components are in good condition upon delivery, but successful assembly requires familiarity with soldering and basic electronics. Batteries are NOT included. Shell screws are nylon — please refer to product images. Made in Mainland China.

Key Features

60 Rotating LEDs simulate a sweeping second hand with multiple dynamic animation modes to choose from
6 Time Animations + 4 Offline Animations — visually engaging display modes for any environment
Temperature & Time Alternating Display — monitor both at a glance without checking your phone
Configurable Alarm — set, enable, or disable an alarm with just 2 onboard buttons
Power-Off Memory — retains time settings even after power is disconnected
Automatic Light Control (LDR) — brightness of the LED display and digital tube adjusts automatically to ambient light; also works as a subtle night light

Frequently Asked Questions

Q: Do I need to program the microcontroller myself for this DIY clock kit?

A: No programming is required. The 51 SCM microcontroller comes with the firmware pre-burned and installed. Simply solder the through-hole components together following the included guide, connect a 5V USB power source, and your rotating LED digital clock will be ready to use straight away.

Q: What power source does this LED digital clock kit use?

A: This kit runs on 5V DC power, making it compatible with standard USB phone chargers, power banks, and computer USB ports. Batteries are not included and are not required for normal operation.

Q: Is this clock kit suitable for beginners?

A: This kit uses full through-hole (plug-in) components, which are the most beginner-friendly type for soldering. However, basic soldering experience and familiarity with circuit assembly are recommended for best results. It is ideal for electronics students, hobbyists, and makers looking to build their skills with a rewarding, functional project.

Q: Can the LED brightness be adjusted automatically?

A: Yes! The kit features a built-in light-dependent resistor (LDR) for automatic ambient light sensing. The brightness of both the digital tube display and the LED ring will automatically adjust based on the surrounding light level. This feature can also be toggled on or off using the onboard buttons, and the display can serve as a soft night light in dark environments.
