LED is an acronym for Light Emitting Diode, which is made from compound semiconductors such as gallium (Ga), arsenic (As), and phosphorus (P). Gallium phosphide diodes emit red light, gallium arsenide diodes emit green light, and silicon carbide diodes emit yellow light. The reverse breakdown voltage of LEDs is 5V. The forward current-voltage characteristic curve is very steep, so the module includes an onboard current-limiting resistor to control the current flowing through the LED when in use. RGB stands for Red, Green, and Blue channels, which is an industry color standard. By adjusting the three channels and combining them, various new colors can be displayed. Statistically, it can create 16,777,216 different colors.
