If you like NeoPixel strips you’ll love these 5mm clear through-hole NeoPixels. All the single-pin-controlling-hundreds-of-LEDs goodness in a breadboard friendly format. Each LED looks just like a shorter version of the classic through-hole 5mm RGB LED with 4 legs, but instead of just red/green/blue there’s a little chip inside that can control the LED with high speed PWM for 24-bit color.
Power them with 5V and chain them together, tying the Data-Out pin of one to the Data-in of the previous one in the chain. If you’re using an Arduino, you can control these LEDs with our wonderfully-written Neopixel library for Arduino. They also work great with our Trinkets. Note that these are “RGB” instead of “GRB” format used in the 5050-sized LEDs you are so used to. Check in the NeoPixel example code for how to swap the colors automagically.

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.
