Camera module software

This folder contains the code running on the camera module, an ESP32-CAM module. It has /capture endpoint serving an image of the remote.

Setup to work with the ESP32-CAM

Arduino IDE

To work with this existing project, open the esp32-cam.ino file with Arduino IDE.

  1. In File>Preferences in the field Additional boards manager URLs add the following two lines:
https://arduino.esp8266.com/stable/package_esp8266com_index.json
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
  1. In Tools>Board>Boards Manager install the esp32 package.
  2. In Tools>Board>esp32 select AI Thinker ESP32-CAM
  3. For the Serial connection, set the baud to 115200 (dropdown at the top right of the serial console).

Setting the WIFI credentials

The WIFI credentials (SSID and Password) are set in the main Arduino project file: esp32-cam.ino. At the top of the file (line ~35) the credentials have to be set in the following lines:

// ===========================
// Enter your WiFi credentials
// ===========================
const char* ssid = "wifi-ssid";
const char* password = "wifi-password";

Flashing

GND and IO0 need to be connected while powering on the ESP for it to boot in flashable mode. Use a cable to connect them. To boot the flashed program, remove the cable and reboot (i.e. power cycle) the ESP with the two pins not connected.

Wiring

wiring schema for flashing as described in the Course Handbook in Chapter 25.4
note the two pins that need to be bridged (only) during flashing
