Enhancement for ESP32-CAM Camera modules to detect movement start / stop using image centre of mass shift. This works on small bitmaps so allows large frame JPEGs to be captured whilst on the fly analysing for motion changes.

Enhancement to Arduino CameraWebServer sketch for ESP32-CAM Camera modules to record JPEGs to SD card as frame rate controlled MJPEG video on external interrupt eg PIR for security camera, and subsequently select videos to playback at recorded frame rate from SD card to browser. https://github.com/s...

You cant use pinMode() in Arduino to set pins 32 & 33 to output as they are on a separate bus to 0-31 You can add the following function to your sketch however (that I created for my purposes based on someone else's work), and call as e.g. aPinMode(32, OUTPUT); void aPinMode(int pinNum, int pinDir) ...

Could be induced voltage on the connection between pot and pin. Put a 100nF cap as close as possible to pin and ground and use exponential filtering in software.

The IEEE convention is uppercase B for bytes, lower case b for bits, so 4MB = 4M bytes = 32M bits

Maybe the library you are using does not pass on that reason code so you have to use a lower level function - check the source code of the library you are using.

I use both esp8266 and esp32 with arduino ide, and the support has matured over time. Now that esp32 arduino can be installed from the boards manager it is straightforward, but some libraries need to be manually installed. Esp32 has more features but more expensive than esp8266. Ignore lua for now, ...

Thanks, updating to latest fixed issue. I notice that a 'major WiFi overhaul' was committed on 24/06.

There are pads on a PCB and pads on a silicon wafer, the pins bridge the gap for the pads in use. A gpio is a service connected to a pad, which may be connected to a pin, which may be connected to a PCB.

If your phone support otg you can use an otg cable and a USB terminal app. I use this on my android tablet
