I recently built a Raspberry Pi-powered night-vision camera to view hedgehogs* and other wildlife in my garden.
(* NOTE: The aim of this project was to photograph hedgehogs in my garden, which is in the UK. According to Wikipedia, there are no species of hedgehog native to North America, which I imagine accounts for most of the Make: audience, but there is nothing in this project that is specific to hedgehogs.)
I used a Raspberry Pi night vision camera – a 5MP infrared camera module with IR LEDs – which is perfect for taking pictures at night, and also works well during the day. I also used a Long-range WiFi dongle with antenna – this allows the device to get a WiFi signal at the end of my garden so I can connect in.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
