Ever wonder who comes to your door during the day while you’re gone? Here’s a simple DIY project to answer that question. Every time someone rings your doorbell, you’ll receive a text message containing a photo of the person. The system can also be setup to automatically take photos based upon motion detection instead of a doorbell press.
When someone rings the doorbell, the Arduino instructs a camera to take a picture. It then also sends an email to your smart phone notifying you that someone is at the door. If you’re nterested in building your own, check out the detailed instructions.
