Hello Guys,
I'm a German student. I have to build a "home security system" for my studies.
Basically, the system consists out of a few sensors monitoring a door of a room. If someone enters the room, the sensors detect the "someone" and a camera should be triggered. The picture should be sent to the phone of the room owner. The sensors are powered with an Arduino Uno R3, the Uno should trigger a ESP32 with a Camera mount to make the photo and sent it with the WiFi capabilities of the ESP32. The picture should be sent to the phone of the room owner. I decided to do this with a Telegram bot.
My prof got me a board with a Espressif ESP32-Wrover and a V1.0 Camera. This board is from Elegoo. To be precise, from the Elegoo Smart Robot Car Kit V4.0. It is the module on the front end of the robot.
I already uploaded a WiFi scanner Code to the ESP32, and it works, I just can't get the cam to work. The Telegram Bot connection also works. This is my Error message: (Error: Camera probe failed with error 0x105(ESP_ERR_NOT_FOUND)
Camera init failed with error 0x105).
My questions are:
Troubleshooting guids often claim a common couse for problems are the wrong Pins. How do i find out the right pins for my board? I have original Code files from Elegoo for the original Robot Car Kid, and i use the same Pin initialization.
Is the Cam also powered by the USB Port to program the ESP32 Chip? Or do I have to provide power through the VCC (with Ground) Pin at the bottom of the Board? There are also a TX and RX pins, are those Pins connected to the Cam or the ESP32?
From my understanding, the RX and TX are used for communication between the cam and the ESP32. However, the Cam is mounted on a board with the ESP32 by Elegoo so i cant imagine i have to connect the RX and TX with the ESP32 for it to work.
Thank you for your help and time in advance, and maybe someone knows what to do.
With best regards hurgel
