안녕하세요. 마스터님
문제점
*서보 모터
- 서보모터 단독 코드일때는 잘 움직임
- 그러나 네오픽셀과 초음파 mp3 코드와 같이 있으면 이상 작동
- 전에 주신 코드는 작동을 잘하나 mp3코드가 들어오니 또 모터가 이상 작동을 합니다.
감사합니다.
탭으로 구성해서 코드가 나뉘어져 있습니다.
const int trigPin = 6;
const int echoPin = 7;
long duration;
int distance;
void setup() {
pinMode(trigPin, OUTPUT); // trigPin을 출력으로
pinMode(echoPin, INPUT); // echoPin을 입력이다.
Serial.begin(9600);
distanceneopixel_setup();
distanceservo_setup();
distancemp3_setup();
}
void loop() {
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance= duration*0.034/2;
