The research on robots has made significant progress, and theoretically, all mechanical labor can be replaced by robots. From the increasingly mature industrial robots and mobile robots, it seems we are witnessing a historical repetition that once occurred in computer systems: transitioning from mainframes to workstations, and now to personal computers and handheld devices. In … Read more

Of course, below I will provide a complete example of Arduino serial communication. This example will demonstrate how to perform simple data exchange between Arduino and a computer. We will write a program that receives characters from the computer and performs different actions based on the received characters. At the same time, Arduino will also … Read more
1. Hardware Preparation You’ll need an Arduino development board (such as Arduino Uno) and several LED lights. Connect the anode (long leg) of the LED lights through a current-limiting resistor (usually a few hundred ohms, such as 220Ω, to prevent excessive current from damaging the LEDs) to the digital pins of the Arduino board (for … Read more
100 Essential Points in Computing 1. The symbolization of information is data, so data is the concrete representation of information, and information is the logical meaning abstracted from data. 2. Information technology refers to the technologies related to acquiring, storing, transmitting, processing, developing, and utilizing information resources. 3. The core of culture is: ideas and … Read more
Hello everyone, I am Pi Zi Heng, a serious tech person. Today, I will talk about project files in embedded development. In the previous two lessons, I introduced two typical input files in embedded development: source files (.c/.h/.s) and linker files (.icf). I want to ask again, are there any other input files? The answer … Read more
