The ceiling of the mosque’s forecourt supposedly resembled Mike’s brown hair. The layering of two Visigothic archways supposedly resembled the area between Mike’s hairline and the edge of his brow. Finally, the related alignment of the Moorish cusped arches with their striped stonework resembled Mike’s eyes and nose just enough that the software thought a 10th-century mosque was the face of a 21st-century human.
Rather than viewing this as a failure, I realized I had found a new insight: Just as people’s faces have features that can be recognized by algorithms, so do buildings. That began my effort to perform facial recognition on buildings – or, more formally, “architectural biometrics.” Buildings, like people, may just have biometric identities too.
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. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
