ESP32-Timelaps

ESP32-Cam TimeLaps project with servos control, settings storage, and many functions. Adjust your camera settings, prepare your trajectory, set your timelaps preference and start it. Exemple of trajectory on youtube:

I used the code from bitluni to learn the web interface and prepare the base for future projects: bitluni/ESP32CamTimeLapse. Web interface joystick code from bobboteck/JoyStick. Servos kit can be found on aliexpress for cheap!

Features

• Fully controlled through the web interface
• All settings in EEPROM
• 3 sets of settings available to store/load on demand
• AutoStart
• WiFi Station & AP WiFi
• WiFi can be disable while running
• Memory information and management
• SDCard can be initialize while running
• LED Flash fully configurable (dimmable)
• Two axis servos arm can be controlled with the joystick from the web interface
• Configurable trajectory to track object during time laps (preview available embedded)

Configuration

• All parameters controllable from web interface
• Select/comment camera board in src\camera.cpp according to your board
• According to your camera behavior, set the camera frequency in camera.h "config.xclk_freq_hz" to get good images. Mine works at 5MHz.
• Serial pins are used for Serial or Servos. Set your configuration in "debug.h"

Create video from img using W10 Photo

• In Windows Explorer, select all files you want to include in the video
• Right click on selection -> Property -> Details
• Select a random date on the "Origin -> Date taken" property, then apply
• Use native W10 Photo to create video

Create video from img using fffmpeg

JackGruber/ESP32-Timelaps-Webcam

To Do

• Add embedded picture rotation
• Add camera frequency in settings
• Add deep sleep function during time laps
• Add settings to maintain command or to power off servo when not moving
• Add servo speed control loop somewhere (use of ESP fade timer hardware function can be great)

Limitation

• Fast movements can reset the ESP32-CAM : power supply glitches
• Servos might generate steps because of servos specifications. PWM SW resolution is much better than my servos resolution.
• Trajectory path follow the function Y=AX2+BX+C. X is servos X (ROTATION) Y is servo Y (UP/DOWN). Set your Start/Mid/End points accordingly: Mid point should be SOMEWHERE IN BETWEEN the others.
