1、数字震动传感器

本开关在静止时为开路（OFF）状态，当受到外力碰触而达到适当震动力时，或移动速度达到适当离（偏）心力时，导电接脚会发生瞬间导通（ON）状态，使电气特性改变，而当外力消失时电气特性恢复开路（OFF）状态。无方向性，任何角度均可以触发工作。

#include <Adafruit_NeoPixel.h>

#define PIN_LED 16
#define NUM_LED 1
int shake =25;
Adafruit_NeoPixel pixels(NUM_LED, PIN_LED, NEO_GRB + NEO_KHZ800);
void setup() {
// put your setup code here, to run once:
pixels.begin();
pinMode(shake, INPUT);
pinMode(16, OUTPUT);
Serial.begin(9600);

}

void loop() {
pixels.clear();
int State = digitalRead(shake);
Serial.println(State);
if(State==0){
pixels.setBrightness(200);
pixels.setPixelColor(0, pixels.Color(int(random(0,255)), int(random(0,255)),int( random(0,255))));
pixels.show();
delay(2000);
pixels.setBrightness(0);
pixels.show();

}
