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.

Standalone Momentary Capacitive Touch Sensor Breakout – AT42QT1010: This breakout board is the simplest way to create a project with a single “momentary” capacitive touch sensor. No microcontroller is required here – just power with 1.8 to 5.5VDC and touch the pad to activate the sensor. Read more.
