“Meter Crawler” is a normal steel measure crawls like a snail. It combines the movement of measuring and moving of snail. It is combined functions of objects and organic movements or human behaviors. Physical objects animate like animals or insects. A meter crawler protrudes its steel measure four or eight cm. The body of the crawler follows the steel measure and thus moves forward. When it is taken away from floor, it stops moving, and the steel measure holds into the case. When it is on a floor, it starts protrudes its steel measure and move forward.

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.
