How to Program

ESP32-CAM Project Ideas

Backup Camera
Use as camera module for backup camera for truck with RPi or Arduino-based dashboard monitor, connected via WiFi or Bluetooth.
Issues to be solved:
  • Power supply
  • Weather-proof case
  • External antenna?
  • Need for WiFi router? (Module acts as a hotspot according to one tutorial)
Robot Vision
Embed in a DIY robot, making use of the built-in facial recognition software to allow the robot to recognize individuals and greet them by name.
Front Door Security System
Connect a motion detector to an ESP32-Cam to send an SMS message to a smartphone with an image of whomever is at the door.

IDEs to use with ESP32

A variety of IDEs work with the ESP32. Arduino IDE is fine, but the RandomNerd MicroPython ebook recommends uPyCraft IDE. I've installed both on Win10.
