This development demonstration video utilizes the Arduino Nano Matter Board and the SR602 PIR sensor to create a Matter over Thread occupancy sensor, showcasing how to set up a routine in the Amazon Alexa application to turn lights on and off when the occupancy state changes. Another version of the code runs solely on the … Read more
Do you want to set up a weather station at home to monitor temperature and humidity changes anytime, anywhere? Then try this mini weather station! We will use Arduino, the DHT11 temperature and humidity sensor, and an OLED display to build a super cool weather monitor. Don’t worry, despite the long name, the actual operation … Read more
Overview Gas leaks are common safety hazards in daily life, whether it’s a gas leak in the kitchen or toxic gases elsewhere, the problem can occur at any time. Although there are many smart devices in modern homes, it would be perfect if even the “air” could be a little smarter! This project develops a … Read more
Arduino and Photoelectric Sensors: Automatic Counter Design In industrial production, product counting is a fundamental and important process. This article will introduce how to use Arduino and photoelectric sensors to create an automatic counter that achieves the function of automatically counting objects as they pass by. This project is suitable for beginners and helps to … Read more
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
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
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
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
