These LED augmentations can help you with your cyberpunk costume or other design that requires glowing eyes. this is a super cheap, simple circuit comprised of a battery and LEDs. You will need patience and a steady hand, however.
Make sure your soldering iron has a fine tip and use SMD LEDs in size 1206. This size has about a 1mm distance between the terminal foot and the top of the acrylic cap, allowing a 1mm enamel wire to sit in that gap very comfortably.
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.
