Basic ESP32-CAM sketch

About the sketch presented here:

Script based on the fantastic tutorial "ESP32-CAM Take Photo and Save to MicroSD Card" written by Rui Santos at Random Nerd Tutorials
Original tutorial in: https://randomnerdtutorials.com/esp32-cam-take-photo-save-microsd-card/

Activities of the sketch:

The original sketch, written by Rui Santos, the ESP32-CAM takes a picture and then enters in sleep mode.
The sketch here implements a slight modification. Now, the ESP32-CAM doesn't goes to the sleep mode after taking a picture.
It takes a picture every 60 seconds and saves it in the MicroSD card attached to the ESP32-CAM.

Circuit for uploading the sketch to the ESP32-CAM:

The diagram above uses an FT232R programmer to upload the sketch to the ESP32-CAM.
Connections:
- IO0 (ESP32-CAM) - GND (ESP32-CAM)
- GND (FT232R programmer) - GND pin (ESP32-CAM)
- VCC (FT232R programmer) - 5V pin (ESP32-CAM)
- TX (FT232R programmer) - U0R pin (ESP32-CAM)
- RX (FT232R programmer) - U0T pin (ESP32-CAM)

Pictures:

The picture above shows the ESP32-CAM in programming mode, using a FT232R programmer module.
Don't forget to connect the IO0 and GND pins of the ESP32-CAM (yellow wire in the picture abore).

After uploading the sketch to the ESP32-CAM, disconnect it from the PC and remove the yellow wire.
Then, connect it again to the PC (or in power) and then it will work!
It will take a picture every 60 seconds and save then in the attached MicroSD card.
