#include <analogWrite.h> //請安裝ESP32 AnalogWrite程式庫
void setup() {
  Serial.begin(115200);
  pinMode(15, OUTPUT);
}

void loop() {
  Serial.println("由暗變亮");
  for (int i = 0; i <= 255; i++) {
    analogWrite(15, i);//亮度i從0->255
    delay(10);
  }
  delay(1000);
  Serial.println("由亮變暗");
  for (int i = 255; i >= 0; i--) {
    analogWrite(15, i); //亮度i從255->0
    delay(10);
  }
  delay(1000);
