On récapitule:

• Install API Arduino
• Download https://github.com/me-no-dev/ESPAsyncWebServer/archive/master.zip
• Install: Menu Sketch → Include Library → Add .ZIP Library…
• idem pour https://github.com/me-no-dev/AsyncTCP/archive/master.zip
• /!\ Board ESP32 by Espressif v3.1.0 incompatible → v3.0.7 (Menu Tools → Board → Boards Manager → Search Esp32, remove v3.1.0 and install v3.0.7)
• Code: https://github.com/RuiSantosdotme/ESP32-CAM-Arduino-IDE/blob/master/ESP32-CAM-Take-Photo-and-Display-Web-Server/ESP32-CAM-Take-Photo-and-Display-Web-Server.ino
• Contrairement à ce que le code dit, il faut sélectionner le board ESP32 Wrover Module
• Press FLASH, press RST, let RST, let FLASH
• Menu Sketch → Upload
• Press RST
• L'IP sera indiqué dans la fenêtre Sérial

Ajouter les lignes suivantes: ligne 34:

boolean flashlight = false;

ligne 57:

#define LED_BUILTIN 4

ligne 76:

<button onclick="captureWithFlashlight()">CAPTURE WITH FLASHLIGHT</button>

ligne 89:

function captureWithFlashlight() {
  var xhr = new XMLHttpRequest();
  xhr.open('GET', "/capturewithflashlight", true);
  xhr.send();
}

ligne 108:

pinMode (LED_BUILTIN, OUTPUT);

ligne 182:

server.on("/capturewithflashlight", HTTP_GET, [](http://AsyncWebServerRequest * request) {
  takeNewPhoto = true;
  flashlight = true;
  request->send(200, "text/plain", "Taking Photo");
});

function loop devient:

if (takeNewPhoto) {
  if (flashlight) digitalWrite(LED_BUILTIN, HIGH);
  capturePhotoSaveSpiffs();
  takeNewPhoto = false;
  if (flashlight) {
    digitalWrite(LED_BUILTIN, LOW);
    flashlight = false;
  }
}
