Arduino Camera Tutorial: Capture Photos to an SD Card (TTL Serial VC0706)
Can an Arduino actually take a picture? Yes. In this episode I wire up a VC0706 TTL serial camera, capture a JPEG image, and write it straight to a micro SD card. You'll see the full setup, the library, the snapshot sketch, and two live captures from start to finish.

This camera shoots at VGA resolution (640 x 480) and communicates over UART using TTL logic, which means you need a voltage divider on the RX line so it never sees more than the safe logic level. The SD card side has its own requirements too. The card must be formatted as FAT16 or FAT32, and the chip select (CS) pin has to match what's set in your sketch. In this build CS is on pin 10.
The best part is what this camera can do beyond a single snapshot. It supports continuous capture with built in motion detection, so you can trigger a photo the moment something moves. Not a replacement for a real security system, but a fantastic critter cam for catching whatever is raiding your garbage cans at 2am.

🔧 Who is This For:
Makers who already have a blinking LED under their belt and want to add a real sensor with real output. If you're building a wildlife cam, a time lapse rig, a doorbell project, or you just want to know how image data moves from a camera to storage, this one is for you. Some soldering is helpful since the camera holes are too small for standard header pins.
