Introduction to the circuit

There are 15 RGB LEDs. Each RGB LED has one RED, one GREEN and one BLUE LED inside it. So, there are 15 x 3 = 45 LEDs in total. The connection of these 45 LEDs is explained on next page.

Consider the following circuit

LEDs are connected to:
PD0 LED_00
PD1 LED_01
PD4 LED_02
PD5 LED_03
PD6 LED_04
PD7 LED_05
PB0 LED_06
PB1 LED_07
PB2 LED_08 
PB3 LED_09 
PB4 LED_10
PB5 LED_11
PC0 LED_12
PC1 LED_13
PC2 LED_14 

PC3 LED_RED_COMMON 
PC4 LED_GREEN_COMMON
PC5 LED_BLUE_COMMON

Lets have a detailed look at the components . . . .
