This column will introduce the achievements of science and technology every week, push the latest dynamics, provide a platform for technical exchanges, and also have popular science explanations aimed at younger students. This issue will introduce Raspberry Pi – a … Read more
In the previous article on getting started with Raspberry Pi (Part 3), I introduced how to drive a stepper motor. At that time, the stepper motor driven was a simpler one with lower precision. Today, we will drive a more complex stepper motor. Of course, I will still use Arduino as an example, but I … Read more
In the tenth article of the Raspberry Pi getting started series, we will learn how to use the GPIO. — Anderson Silva So far, this series of articles has mainly focused on the software aspects of the Raspberry Pi, and today we will learn about the hardware. One of the main features that intrigued me … Read more
4.1 Basic Concepts of Serial Communication Serial communication is a commonly used communication method, which refers to data transmission between devices through a Serial Interface. There are several basic concepts of serial communication: 4.1.1 Serial Communication Serial communication refers to the transmission of data bit by bit, transmitting only one bit at a time. Compared … Read more
MAKER:jnthas／译：趣无尽 This is a Super Mario themed clock, based on ESP32 and a color dot matrix, which is very vivid and interesting. Mario will stand on the stage to hit the bricks to update the time digits. In addition to the Mario dial, we will also create a dial that displays the time in words, … Read more
1. Introduction to Arduino Programming Arduino programming involves using the Arduino Integrated Development Environment (IDE) to write and upload code to Arduino microcontroller boards, typically implemented using an extension of C++ known as the Arduino language. The code is divided into two parts: setup() and loop(). The former runs once during board startup for initialization, … Read more
CSI + DVP camera design principle is simple, understand it yourself. PDN_TX: Different modules have different effective levels, please pay attention. ID_TX: ID_TX is the camera address, not the motor address, and the internal pull-up and pull-down resistors corresponding to ID_TX have different camera addresses. Please let the software driver engineer pay attention. RC / … Read more
