Elabguy LED-Rainbow-V1B 12-LED Rainbow Bar

This tiny LED bar features 12 bright LEDs spanning the colors of the rainbow (red, orange, yellow, yellow-green, green, blue, violet, pink, warm white, and white). Each LED is controlled by a separate transistor and has its own appropriate current-limiting resistor, so only simple (and low power) high and low digital signals are required to turn each LED on and off. Bring your project to life with this colorful LED bar!
