Innovative Circuit Design: Create an Arduino Uno Without PCB Skills

Do you want to play with circuits but don't know how to design a PCB? You can! Before PCBs existed, components were connected directly (as imagined by Teacher Su). In fact, even when we have PCB design issues that require rework, we often use various jumper wires to make our circuits work.

So, even if your PCB design is flawless, occasionally DIYing a circuit without a PCB is also a meaningful endeavor.

Today, let's take a look at a project done by

Understanding the Differences Between Raspberry Pi, Arduino, and Microcontrollers

Follow the blue text and reply with "Entry Materials" to get the ultimate tutorial from beginner to advanced on microcontrollers

By | Wujie (WeChat: 603311638)

The full text is about1383 words, reading takes about 5 minutes

First, the conclusion: microcontrollers are more suitable for commercial products, while Raspberry Pi and Arduino are better for learning skills.

Next, I will introduce their differences:

1. Raspberry Pi

Raspberry Pi and Arduino are both open-source hardware platforms, but they

Upgraded Matrix Clock Open Source Release!

Time flies, and another year has passed in the blink of an eye. I wonder if everyone still remembers that last year around this time I open-sourced the first matrix WiFi clock. Subsequently, I released a shorter upgraded version as a product in my Taobao store, and many friends purchased it to support me, for which I am very grateful. However, later on, due to a busy work schedule, I had no time to produce it, so I took

Using the MQ-2 Smoke Sensor with Arduino

Follow us on our public account,Star Mark Public Account to not miss exciting content

The MQ series sensors are widely used low-cost sensors, commonly applied in gas leak monitoring devices in homes or factories. This article introduces the use of the MQ-2 smoke sensor from the MQ family, and other MQ sensors operate similarly.

1. Working Principle of MQ Series Sensors

The sensitive material used in MQ series sensors is a highly

Getting Started with Arduino Programming: Hardware and Software Preparation

It's fine as long as the solution suits you, there's no need to pursue perfection.

The Arduino integrated board is a small requirement and is not suitable for all scenarios. If you have a need for younger students to learn Arduino or for large classes, you might want to consider it. Of course, there are many products that meet the same needs. The course videos have already started. This is the first update today. If you need equipment, you can contact

Raspberry Pi and Arduino Serial Communication with DHT11

Arduino has a rich set of external interfaces, and the biggest difference from Raspberry Pi's IO ports is that Arduino has analog input interfaces that can measure analog values on IO ports. The communication scheme between Arduino and Raspberry Pi via serial (Serial) generally has two methods: one is through Raspberry Pi GPIO serial communication, and the second is through USB serial communication.

Clearly, the USB serial communication between Arduino and Raspberry

Playing Music with ESP8266: A Hands-On Experience

Set as "Starred", delivering heavy content to you in real-time.

Recently, I wanted to play with audio playback again.

I dug out some previous articles to review.

This time I plan to use M5stickC, the one with a strap that you can wear on your wrist, yes, it looks great.

I had seen this library before, tested it, and then completely forgot about it. Recently, I was struggling with how to play music using Arduino, tested several solutions

Examples of Arduino Applications in Embedded Development

Do you know what Arduino is? Do you know what Arduino can do? Today, let’s get to know Arduino!

Arduino is a convenient, flexible, and easy-to-use open-source electronic prototyping platform.

It includes hardware (various models of Arduino boards) and software (Arduino IDE). It was developed by a European team in the winter of 2005. Its members include Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, David Mellis, and Nicholas Zambetti.

This article shares a case of lighting up an LED using Arduino.

Exploring Arduino with Register Development

Abstract

The commonly used chip for the Arduino development board is the AVR microcontroller series produced by Atmel. The most common one is the ATmega328P, which is widely used in the Arduino Uno development board. Developing AVR microcontrollers using the Arduino platform is very convenient.

The Arduino IDE provides a very simple and user-friendly development environment, making it easy to write and upload code. It provides a simplified set of function libraries and APIs, allowing developers to easily interact with the

Building an Image Recognition Car with Raspberry Pi, Arduino, and TensorFlow

Since I bought my first Arduino kit, I have been involved in robotics for several years, but it wasn't until recently that I started working on complete projects. During this time, two skills opened the door to a new world for me: Python and Linux. Behind them are powerful open-source communities. Once you master these two tools (meta-tools), you will feel that there are plenty of handy weapons
