Fishbowl existence is tough. There you are, bobbing up and down in the same dull old environment, day in, day out; your view unchanging, your breakfast boringly identical every morning; that clam thing in the bottom of the tank opening and closing monotonously – goldfish can live for up to 20 years. That’s a hell of a long time to watch a clam thing for.
Indeed, fishbowl existence is so tough that several countries have banned the boring round bowls altogether. (There’s a reason that your childhood goldfish didn’t live for 20 years. You put it in an environment that bored it to death.) So this build comes with a caveat – we are worried that this particular fish is being driven from understimulus to overstimulus and back again, and that she might be prevented from making it to the full 20 years as a result. Please be kind to your fish.
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, 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.
