DIY Rotating LED Electronic Clock Kit – DS1302 Digital Clock Soldering Project
Category: Kits ► Play ► Electronics Kit ► Starter Kits
Bring the magic of a moving‑display clock to life with this all‑in‑one DIY electronics kit. The 81 mm × 81 mm PCB comes pre‑loaded with a single‑chip microcontroller and a DS1302 real‑time‑clock (RTC) module, so the moment you solder the plug‑in components the clock is ready to run on a 5 V supply (USB, phone charger or power bank). A rotating LED matrix, four eye‑catching animation modes, temperature read‑out, automatic brightness control, alarm and power‑down memory make the finished project both functional and decorative for any desk or nightstand.
Students will master core STEAM skills while building the kit: precise soldering techniques, reading schematic diagrams, and troubleshooting real‑world circuits. They’ll explore how a microcontroller interfaces with an RTC, temperature sensor, and light‑sensor, learning the fundamentals of time‑keeping, data acquisition, and PWM‑driven LED control. The project also introduces basic programming concepts—such as timer interrupts and conditional logic—through the already‑burned firmware, giving learners a tangible sense of how software drives hardware.
Key Features
- Compact 81 mm × 81 mm PCB with pre‑programmed firmware
- 5 V operation via USB, phone charger, or power bank
- DS1302 RTC for accurate timekeeping with backup memory
- Rotating LED display plus six built‑in time animations and four decorative light patterns
- Integrated temperature sensor and ambient‑light sensor for auto‑brightness adjustment
- Alarm function, beeper, and user‑adjustable buttons for full control
Because the kit blends Science (temperature, light, time), Technology (microcontroller, sensors), Engineering (circuit design, soldering, system integration), and Art (LED animations, visual aesthetics), it delivers a complete STEAM experience. Safe, hands‑on, and highly rewarding, this project ignites curiosity, builds confidence, and gives students a showcase‑ready electronic masterpiece they built from the ground up.
