Description
Once soldered, the kit becomes a robot-shaped electronic clock that displays time, year, month, day of the week, temperature. Green digital tube is clear and easy to read. It's not just a soldering exercise kit—it's a practical desktop clock that lets you set alarms and reminders. Key Circuit Principles Used in This Kit 1. Time Base and Oscillation Principle A crystal oscillator (e.g., 32.768 kHz quartz) provides a stable clock signal for the chip’s internal oscillator. Principle: The DS1302 clock chip calculates time internally to generate the second, minute, and hour reference signals. 2. Display Driving Principle The DS1302 time data is read and displayed on 7-segment LEDs, controlled by the MCU. Principle: Multiplexing or dynamic scanning is used, with the MCU controlling the illumination of each segment.
