Installation and Setup

How to install FastLED for your development environment.

Difficulty Level: ⭐ Beginner Time to Complete: 10-20 minutes (depending on internet speed and IDE download) Prerequisites: None - this is the software setup step You'll Learn:

• How to install FastLED in PlatformIO (recommended method)
• How to install FastLED in Arduino IDE
• How to manually install from source (advanced users)
• How to verify your installation is working correctly
• What to do after installation succeeds

PlatformIO (Recommended)

PlatformIO provides the best development experience with dependency management, multiple board support, and easy configuration.

Add FastLED to your platformio.ini:

[env:myboard]
platform = ...
board = ...
lib_deps =
    fastled/FastLED

Arduino IDE

1. Open Sketch → Include Library → Manage Libraries
2. Search for "FastLED"
3. Click Install
4. Wait for installation to complete
5. Restart Arduino IDE

Manual Installation

If you need to install from source:

1. Download the latest release from GitHub
2. Extract the archive
3. Copy the FastLED folder to your libraries directory:
   • Windows: Documents\Arduino\libraries\
   • macOS: ~/Documents/Arduino/libraries/
   • Linux: ~/Arduino/libraries/

Verification

Test your installation with this minimal program:

#include <FastLED.h>

void setup() {
    Serial.begin(115200);
    Serial.println("FastLED is installed!");
}

void loop() {
    // Your code here
}

If it compiles without errors, you're ready to go!
