This video describes the hardware and software code required to program an ESP32-CAM board to create a wide range of camera functionality:
Create timelapse videos
Trigger photographs to be taken with a switch, when movement is detected by a PIR sensor, or any other input
Trigger a photograph to be taken when a HIGH signal is sent from an Arduino or other microprocessor
Use onboard LED as a flash
Save photos to onboard SD card, or send them as an email attachment
Power the ESP-32 from a single 3.7V Li-Po battery pack

You can customise this code to make it suitable for, e.g. a wildlife camera, a security camera, or a camera triggered to take "reaction" shots in an Arduino-controlled escape room game. The ESP32 chip can be programmed using the familiar Arduino IDE, or whatever development environment you prefer. For full details of the functionality of the OV2640 camera sensor used in these boards, see the datasheet at https://www.uctronics.com/download/OV...
