RGB LED is the abbreviation of ‘’Red Green Blue Light Emitting Diode’’. RGB LED is the most amazing type of LED which has the ability to create millions of different shades of light colors using red, green, and blue colors.
A light-dependent resistor (LDR) is the light-sensitive device most frequently used to measure the intensity of the light. Light-dependent resistors are also known as photoresistors whose resistance increases as the intensity of light decreases which helps to identify the presence and absence of light.
