ESP-01 모듈로 IoT연습

지난번에 이어

두개의 다이얼로 LED의 PWM 제어

한개는 미사용이고 기능 시험만 해봄.

ESP-01 모듈 소스 스케치

// ============================================================================================
// 외부에서 ESP모듈에 연결된 LED를 그래픽으로 밝기 조절 : PWM at GPIO 2
// Demonstrates realtime LED PWM value update without page refresh
// 'index.h' 화일과 필요한 Jquery & Knotrol.js 화일은 'data' 폴더 안에있다. (SPIFFS로 업로드)
// 주의 : SPIFFS로 업로드 할때 'Serial monitor' 끌것. 올라간 화일은 크기가 좀 커진다.
