声音传感器资料
arduino源程序如下:
- int ledPins[] = {3,4,5,6,7,8,9,10};
- int switchPin = 2;
- int soundPin = 0;
- boolean showPeak = false;
- int peakValue = 0;
- void setup()
- {
- for(int i = 0;i < 8; i++)
- {
- pinMode(ledPins[i],OUTPUT);
- }
- pinMode(switchPin,INPUT);
- }
- void loop()
- {
- if (digitalRead(switchPin))
- {
- showPeak = !showPeak;
- peakValue = 0;
- delay(200);
- }
- int value = analogRead(soundPin);
- int topLED = map(value,0,400,0,12)-1;
- if(topLED>peakValue)
- {
- peakValue = topLED;
- }
- for(int i = 0;i < 8;i++)
- {
- digitalWrite(ledPins[i],(i <= topLED||(showPeak && i == peakValue)));
- }
- }
