You can use almost any 3mm or 5mm LED with the Quirkbot, just cut the leads to the right length. (See hardware documentation: LEDs (soon!))

The change in brightness of the LED is achieved by a method called PWM (Pulse Width Modulation). There are many YouTube videos and tutorials explaining this concept, like the beginning of this video.
