You’ve probably seen a sailboat at some point—but maybe not a “sailcar.” Why don’t we have more wind-powered cars? Sailboats must zig-zag back and forth if they want to sail directly into the wind. It probably wouldn’t be very safe if we had cars zig-zagging all over the road on a windy day! Although it might not be practical to use a sailcar on the road in real life, building a toy one is a fun engineering project.
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.
