Innovative Points

　　This project attempts to introduce wing layouts into ground effect vehicles, aiming to compensate for the shortcomings of both through complementarity and innovation. The wing tips are equipped with two vertical stabilizers with control surfaces, allowing the vehicle to achieve no roll yaw during ground effect flight, avoiding wing-ground friction; the vehicle's control system is entirely self-developed, centered around an Arduino Mega 2560

Guide to Choosing Development Boards (Part 1) – MCU

In the previous article, we briefly introduced how to choose development boards in different fields, but many people are still confused because we didn't recommend specific models. In this article, we will look at what types of development boards are suitable for specific fields.

Here, I will recommend development boards based on the performance you need, starting with the lower-performing MCU chips.

MCU (Microcontroller)

This is actually the most commonly used type of development board, which is needed in various aspects. The main

DIY Laser Engraver Guide

1. Main Hardware Components: (Making Two Axes)

1. Two desktop CD drives

2. Two Easydriver stepper motor drivers

3. One Arduino UNO R3 development board

4. One relay module

5. One 100mw blue-violet laser head

It is the simplest and most convenient to make a laser engraver based on the reference prototype, and it only involves two-axis movement. Essentially, you just need to find two CD drives and assemble them at a 90-degree angle to complete the project. However, considering that lasers can be dangerous and

Which is Better for Beginners: Arduino or 51 Microcontroller?

The development of microcontrollers has led to a wide variety of models available today, seen in everyday appliances like rice cookers, remote controls, and washing machines, all controlled internally by microcontrollers. The microcontrollers used in these products are customized and are not the same as those we use for learning.
Many beginners may still be torn between choosing Arduino or the 51 microcontroller to start with. Arduino is a platform developed based on the AVR microcontroller, while the 51 microcontroller is

Getting Started with Arduino UNO R3

I purchased the Arduino UNO R3 development board for 23 yuan. Because it is relatively expensive, its board and chip are consistent with the official version priced at 88 yuan. The USB to serial converter uses either the ATmega16U2 or ATmega8U2.
Specifications:
■ Operating Voltage: 5V
■ Input Voltage: No external power supply is required when connected via USB or external 7V~12V DC input
■ Microprocessor: ATmega328P, with a write/erase cycle of 10,000 times, priced at about
