How to Program
ESP32-CAM Project Ideas
- 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)
- 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.
ESP32/8266 MicroPython Projects
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.
My ESP32 Boards
- I bought a 2-pack of 30-pin ESP32 DevKit boards from Amazon on 30 Nov 2020, for $11.95 on their CyberMonday special.
- After hearing Gary Fleming talk about it, I also bought an ESP32-CAM in January 2021.
- This board is an excellent platform for developing with the ESP32 SoC, a single chip solution that combines Bluetooth and 2.4 GHz Wi-Fi capabilities. Different than our other development board, this one includes a OV2640 camera that communicates with the ESP32 over I2S and has a resolution of 1600×1200 pixels. It also carries a micro SD card adapter for applications requiring additional storage space. The ESP32-CAM is a development platform that combines the tried and true ESP32 SoC with an integrated camera. With a 27×40.5×4.5mm footprint and a deep sleep current of up to 6mA, the ESP32-CAM provides an excellent platform for creating computer vision projects! Features: Processor: ESP-32 Onboard camera: OV2640 Camera resolution: 1600×1200 pixels; JPG output Operating voltage: 3.3V Camera interface: I2S Color depth: 8-bit 16M colors Please note this board doesn't carry a USB-to-Serial UART adapter (e.g., CP2102, CH340g) so you'll need to connect one to its TX/RX pins and/or set it up for OTA.
