I have built a Ηouse (shelter) for stray cats in my neighborhood. As I saw that most people are not interested in them, I thought of offering them a small gift.
The construction is made of pallet wood. I have also installed a heated pillow, a WiFi camera, and a light. I power all these systems from an old computer power supply which I call a "control box".
The food is transported by a crane, which I control remotely via a smart phone, to make the crane, I use the ARDUINO UNO.
