Getting Started with Arduino: The Magical Development Board for Everyone to Become a MakerA small board unlocks the Internet of Things, allowing anyone with no background to play with smart hardware!
๐ Introduction
Have you ever thought aboutโโ Controlling the lights in your home with your voice?โ Automatically watering your plants and alerting you when they lack light?โ Using code to command a robotic arm to draw Van Gogh’s Starry Night?
A palm-sized Arduino development board can make these ideas come true! Today, letโs unveil the secrets of this “electronic LEGO” and experience the joy of hands-on creation!
๐ What is Arduino?
โ Hardware: Open-source microcontroller board + pluggable sensor modules (supports hundreds of peripherals like LEDs, motors, temperature and humidity sensors, etc.)โ Software: Simplified programming based on C/C++, drag-and-drop code library for one-click invocationโ Soul: Solutions shared by the global open-source community, allowing beginners to replicate expert projects!

๐ Five Reasons Why Arduino is So Popular
1๏ธโฃ No barriers: USB directly connects to the computer, even elementary school students can light up an LED in 3 minutes!2๏ธโฃ Inexpensive: Mainboard ยฅ50 + sensor ยฅ5, the cost of a cup of milk tea opens the path to becoming an inventor!3๏ธโฃ Strong expandability: With WiFi/Bluetooth modules, easily create a home IoT!4๏ธโฃ Open-source ecosystem: Millions of projects on GitHub, just copy and paste to use!5๏ธโฃ Educational tool: A STEAM teaching tool used by Tsinghua University Affiliated High School and Silicon Valley geeks!
๐ฎ Cool Cases: Discover How Fun Hardware Can Be!
๐ Case 1: Smart Farm Assistant๐ง๏ธ Soil dry? Automatically water!โ๏ธ Insufficient light? The supplemental light turns on! (Cost: 1 temperature and humidity sensor + 1 water pump + 1 Arduino)
๐ Case 2: Interactive Figurine๐ค Wave to switch expressions, touch to play voice (Core: 2 servos + 1 touch sensor + 1 MP3 module)
๐ Case 3: Office Anti-Distracting Device๐ป Detecting TikTok? Automatically disconnect the internet! (Hardware: 1 human infrared sensor + 1 relay)
๐ง Newcomer Must-See: Complete Your First Project in 3 Steps
๐ Goal: Control an LED to blink with Arduino
1๏ธโฃ Hardware Connection
- Connect the long leg of the LED to digital pin 13
- Connect the short leg in series with a 220ฮฉ resistor to GND
2๏ธโฃ Code Copy (Open Arduino IDE)
void setup(){pinMode(13, OUTPUT);}
void loop(){
digitalWrite(13, HIGH);// Light
delay(1000); // Wait 1 second
digitalWrite(13, LOW); // Off
delay(1000); // Wait 1 second
