light dependent resistor
A ____ _________ ______ or a photo resistor or photocell is a light controlled variable resistor. Its resistance changes with light intensity that falls on it
Photo Conductivity
As the intensity of the light increases, the resistance decreases
dark resistance
When a light dependent resistor is kept in dark, its resistance is very high. This resistance is called ____ _________
Red, Green, and Blue Light Emitting Diode
RGB LED stands for:
Common Anode
Common Cathode
Types of RGB LEDs:
Common Anode
Types of RGB LEDs:
This type has a common positive connection for the red, green, and blue LEDs. To control the colors, you connect the cathodes of each color LED to the ground through appropriate resistors
Common Cathode
Types of RGB LEDs:
This type has a common negative connection for red, green, and blue LEDs. To light up the colors, the anodes of each color LED are connected to a positive voltage through resistors
