A quick intro to POV or persistence of vision: Any AC voltage light is actually blinking on and off at a frequency of 60hz or 60 times per second. Our brains perceive this as constant light. It is this concept which we will be taking advantage of, in order to create a spherical image using a single row of LEDs. We used 58 LED for each half. So you need totaly 116 LEDs. And will use a 3D printer for circle. You will find details on video.
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.
