Arduino Rainwater Sensor Interface Tutorial: Detecting Rainfall and Measuring Rainfall Intensity

Arduino Rainwater Sensor Interface Tutorial: Detecting Rainfall and Measuring Rainfall Intensity

Introduction Have you ever been caught outside by a sudden downpour, staring helplessly at the dark clouds above? Or have you thought, “How great would it be if I could know in advance that it was going to rain?” Perhaps you want to create a smart rain alert system but don’t know where to start? … Read more

Arduino Rainwater Sensor Tutorial: Working Principle and Smart Applications

Arduino Rainwater Sensor Tutorial: Working Principle and Smart Applications

Introduction Have you ever thought that rainwater can not only wet your shoes but also trigger smart devices? Imagine, as soon as a drop of rain falls, your window “intelligently” closes to prevent your sofa from turning into a “wet sponge”; or your Arduino suddenly pops up to remind you: “Don’t go out, you’re not … Read more

How to DIY a Raspberry Pi – ARM-Linux Card Computer

How to DIY a Raspberry Pi - ARM-Linux Card Computer

A few years ago, I planned to use a Raspberry Pi to build a small robot, but when I actually started working on it, I found that using someone else’s designed board was not very convenient. On one hand, the Raspberry Pi is designed for a wide range of users, which limits customization; the shape, … Read more

Creating a Schedule Clock with Google Calendar Using Raspberry Pi

Creating a Schedule Clock with Google Calendar Using Raspberry Pi

MAKER: samvanhook / Translated by: Fun Endless Cherry Frequently checking schedules across different platforms (such as mobile calendars, emails, collaborative work platforms, etc.) can often distract people. Is there a way to unify these fragmented schedules into a small device? The answer is yes! Below, we will create a clock project to solve this problem. … Read more

The Journey of Digital Tubes

The Journey of Digital Tubes

Arduino Design Course (Part 3) The Journey of Digital Tubes Course Introduction When numbers dance gracefully with light and shadow on the circuit board, digital tubes compose a brilliant visual poem of electronic magic. In the galaxy of electronic creativity, digital tubes serve as glowing cipher books, transforming numerical language into the rhythmic dance of … Read more

Arduino Basic Experiment 2: Breathing Light Experiment

Arduino Basic Experiment 2: Breathing Light Experiment

In the previous experiment, we learned about the principle of the running light—multiple LEDs lighting up and turning off in sequence. In this experiment, we will learn how to implement a breathing light using Arduino. Unlike the running light, the breathing light achieves a “breathing” display effect by gradually adjusting the brightness of the LED.1. … Read more
