Protei_007 is the seventh prototype for a project called Protei, which is an open source, articulated, segmented, robotic, unmanned, sailboat, originally built to sail upwind, dragging a long oil-absorbent boom, to aid in the cleanup of oil near spill sites. However, Protei is being developed into a more modular and adaptable design for an affordable, easy-to-build, boat, that can be utilized for various purposes, including nuclear waste monitoring, biological sampling, and plastic trash collection.
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.
