Cheap Remote Camera
Here is another inexpensive ESP32/ESP8288 microcontroller project. A few months ago, I bought an ESP32-CAM board.
It had some bad solder joints that took me a while to fix. It works fine after repair.
This little board contains a camera (still and motion), built in flash, 32-bit microcontroller, SD card writer,
512k + 4M memory, Bluetooth, and Wi-Fi for under $7.00. Amazing.
Although this little board has been out for a while the software libraries do not seem very mature.
To test it out, I wrote a program that takes pictures and stores them in on-board memory or on a µSD card.
The images can be retrieved using our old friend FTP.
Pushing a button on a web page created by the microcontroller triggers a picture to be take.
Of course, I did not have to write the program from scratch. Examples were available for all major software components.
This little device could be made into a DIY video doorbell or motion detecting security camera.
