I'm working on the Adafruit Firewalker shoes.

I can't make my code compile to test my flora project.

This is my error message:

Arduino: 1.6.7 (Windows 10), Board: "Adafruit Flora"

C:\Users\Devi\Documents\Arduino\test_2\test_2.ino\test_2.ino.ino:1:29: fatal error: Adafruit_NeoPixel: No such file or directory

 #include <Adafruit_NeoPixel>


compilation terminated.

exit status 1
Error compiling.

  This report would have more information with
  "Show verbose output during compilation"
  enabled in File > Preferences.


    #include <Adafruit_NeoPixel.h>

const int analogInPin = A9;  // Analog input pin that the potentiometer is attached to
Adafruit_NeoPixel strip = Adafruit_NeoPixel(10, 6, NEO_GRB + NEO_KHZ800);
int sensorValue = 0;        // value read from the pot

void setup() {
  // initialize serial communications at 9600 bps:
 pinMode(9, INPUT_PULLUP); 
  strip.show(); // Initialize all pixels to 'off'


void loop() {
  // read the analog in value:
  sensorValue = analogRead(analogInPin);              
  // print the results to the serial monitor:
  Serial.print("sensor = " );                       

if (sensorValue < 100){
  Serial.println("leds triggered"); 
colorWipe(strip.Color(255, 0, 0), 25);
colorWipe(strip.Color(0, 0, 0), 25);


void colorWipe(uint32_t c, uint8_t wait) {
  for(uint16_t i=0; i<strip.numPixels(); i++) {
      strip.setPixelColor(i, c);
  • Can you please copy and paste the code, and the error message, into your question as text? Not a screen-shot? I can hardly read what the error is. Edit your post and format the code using the code formatting markdown (four leading spaces). For help see Markdown help. You should be able to do this by selecting the code and pressing Ctrl+K to have your browser do this for you.

    Your error message says #include <Adafruit_NeoPixel> but your code says #include <Adafruit_NeoPixel.h> - which do you actually have?

  • @NickGammon I have #include <adafruit_neopixel.h> all I did was copy and paste the source code Commented Mar 3, 2016 at 17:45

I had the same problem, you just have to download the Adafruit Neo Pixel library:

enter image description here


i think issue is in your this path C:\Users\Devi\Documents\Arduino\test_2\test_2.ino\test_2.ino.ino:1:29: fatal error: Adafruit_NeoPixel:

make new arduino file and copy the same code and save it on other folder on desktop or other drive then compile it

Compilation I compiled you same code and my stored path of .ino file is C:\Users\Muhammad Hassaan\Documents\Arduino\sketch_mar04a

enter image description here

  • this did work it still says no directory found for neopixels did I install something wrong all I did was copy and paste source code Commented Mar 3, 2016 at 17:43
  • i think issue is with your library that you have downloaded, please reinstall the Arduino IDE and download the library again with the help of ide then recompile your code Commented Mar 15, 2016 at 5:48
