I'm hoping to get some guidance on a project I am planning. I would like to utilize an Arduino Pro Mini plus a tiny camera that can take pictures. My plan is to also have a bluetooth module hooked up so that when the arduino takes the picture, I can serial.write() the hex of the picture. Would this work with the Arduino Pro Mini? I'm just wondering how it would store the picture data so that I can send it via bluetooth. If this is feasible, could anyone recommend me a small camera that I can buy? Thank you!
Using a camera with an Arduino Pro Mini will be difficult but maybe you should consider something like the ESP32-CAM as it has pretty much all your asking for in a single package. A good video tutorial on it use here.
I'm sure there are lots of small pocket cameras out there with Bluetooth built in, for exactly that purpose.
