I am a huge fan of entomology displays, and wanted to create one that is interactive. When the copper tape on the surface of the frame is touched, the butterflies illuminate through a capacitive touch sensor. The blank white strip of paper to the side of each butterfly shows the name, scientific and common, for a bit of unexpected learning.
I created a box frame that is deep enough to house the paper butterflies along with the Arduino and breadboard. I would liked to have made a larger version with a ton of insects but three ended up being a challenge in itself.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
