Aduino实现音频频谱效果

看到这样一个效果，于是想用arduino实现类似效果。需要的组件如下

1 arduino开发板

2 音频传感器

3 灯带

接线图如图

代码如下

#include #include #define PIN 2 // input pin Neopixel is attached to#define NUMPIXELS10 // number of neopixels in stripAdafruit_NeoPixel pixels = Adafruit_NeoPixel(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);int delayval = 1; // timing delay in millisecondsint redColor = 0;int greenColor = 0;int blueColor = 0;void setup() {pixels.begin();Serial.begin(9600);}void loop() {int val=analogRead(A1);Serial.println(map(val,0,1023,1,10));show(map(val,0,1023,1,10));//del
