In all fairness this collar could be used for all types of animals – or humans. Regardless of what creature species you design your collar for the Medium blog post detailing its creation is inspiring!
I’ve been playing around with hardware for the past year. Mainly, I’ve been interested in making little, useless things that flash and glow all colors of the rainbow with LEDs. I’m not super interested in using hardware for home automation or for real practical uses, really. For me, working with hardware is where I can be silly and indulge my child-like wonder. I like creating art or fashionable things whose only purpose is to bring a little joy to those around me (& myself).

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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
