Designing a Programmable Digital Clock with DS1302 and LED Displays
System Overview
This project details the construction of a cost-effective, high-precision digital clock using the DS1302 real-time clock (RTC) chip, a 51-series microcontroller (STC89C52), and 7-segment LED displays. The system provides hour, minute, and second tracking, supports user-defined time adjustment, and ensures data retention during p ...

STM32 Timer Operations: PWM Generation and Input Capture
Pulse Width Modulation (PWM) Overview
PWM is a technique used to simulate analog signal levels by modulating the width of digital pulses. In control applications, such as motor speed regulation, the duty cycle dictates the average power delivered to the load. By rapidly swithcing the output state, the system effectively manages the average volt ...
