Why is PWM dimming considered the “dragon-slaying sword” for electronics enthusiasts? Imagine your LED lights can achieve stepless dimming from a dim candlelight to bright daylight, just like a smartphone screen, by sliding a button. It can even simulate the romantic effect of a breathing light. All of this relies on a magical electronic technique—PWM … Read more
Getting Started with Arduino UNO: Control an LED in 10 Minutes (Includes Code and Wiring Diagram) Introduction: Have you ever thought about using a small Arduino board to make an LED blink, breathe, or even dance to your code? Today, we will unlock the first magic of hardware development with Arduino UNO—controlling an LED! No … Read more
Click the blue text above to follow for continuous updates!!! Introduction Today, we will also not involve the Zigbee protocol, focusing solely on serial operations in the CC2530 microcontroller. This article uses Serial Port 0 for data transmission. The main function is to send serial data from a PC’s serial debugging tool to the microcontroller, … Read more
1. Design Concept For controlling the LED light, we can imagine the functions of the LED light. The first is the switch, brightness, and color, which are the main three functions. How can we abstract these three functions? Regardless of what the underlying LED device is, we can abstract it using this structure. As shown … Read more
C++ and Hardware Interfaces: Embedded Programming and Communication Today, I, Xiao Rui, will take you on a hardcore journey of learning C++, exploring how C++ can directly “communicate” with hardware.Embedded programming and hardware communication is a very interesting yet slightly complex application scenario of C++. Whether it’s lighting up an LED or driving an industrial … Read more
