// Easiest way to get a live web stream:
//
// 1. Tools -> Board -> AI Thinker ESP32-CAM
// 2. File -> Examples -> ESP32 -> Camera -> CameraWebServer
// 3. Edit ssid / password near the top of the sketch
// 4. Find the line "#define CAMERA_MODEL_AI_THINKER" and leave it uncommented
// 5. Upload (hold BOOT button if upload errors)
// 6. Open Serial Monitor at 115200 baud, reset the board
// 7. It prints an IP address - open it in your browser
// 8. Click "Start Stream" - live video appears!

// Capture a JPEG and write it to the SD card
