Lizard Selfies with Raspberry Pi and Java EE #piday #raspberrypi @Raspberry_Pi
Lizard selfies with Raspberry Pi! Via Roberto Marquez on the Oracle blog.
I wrote a Java EE app to manage the enclosure lighting for Chinese water dragons. It uses servlets and cron to control relays attached to the Raspberry Pi GPIO pins.
Recently, I revisited the project to make use of the Raspberry Pi camera for lizard selfies. The application listens for changes on GPIO pin connected to a momentary capacitive touch sensor. When the selfie sensor pin goes high, a photo is taken. Watch his demo series on YouTube.
You can find the capacitive touch sensor on Adafruit. I did not find a Raspberry Pi camera cable in Fritzing, but a standard ribbon cable was used.
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.
