Recently I finished building my second version of a photographer’s LED light stick shown below. A couple years ago I built my first LED light stick to experiment with light painting photographic art. See what I did then at:
The second version is longer than the first stick at 64 inches vs. 48 inches, and has more LEDs: 240 vs. 64. Unlike the first version, it uses a 1 MByte SPI Flash memory chip to store images instead of a Flash memory card. The computer board, an Adafruit Flora (Arduino based), sends image data to Adafruit Neopixel Digital RGB LED strips (144 LEDs per meter). The Flora SPI bus reads images from an external Flash memory chip that was previously programmed over Flora’s USB port from a PC.
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.
