Awesome light painting project from Hackster.io! This one uses a single LED and a custom rig to draw out the image!
Use the concepts in light painting to create a machine that can recreate bitmaps with a long-exposure camera using a single LED.
After watching several videos and seeing numerous articles about light painting, I decided to give it a try. Light painting involves using a camera with a very long exposure time to capture a small light source. This allows for a single of light to become strung out to a long streak in a single image.
But what if someone wants to create a more detailed picture or use many different colors? This is how I came up with the idea to build a 2-axis CNC machine that has a single RGB LED that can change color and “paint” and image.

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.
