RGB Led Driver Shield for Arduino Nano

This is my second project for LED Driver based on CAT4101 IC. The first project was for single White LED. This project has been designed to drive 3 channels of RGB LEDs with PWM signal which helps to create multi-color LED light. Arduino Nano is used to generate PWM signals for RGB LEDs and board has 3 tactile switches and Analog signal input to develop various RGB LED related applications. Each channel can drive load up to 1A and input supply up to 12V DC. 1A X 3 Constant current LED driver shield for Arduino Nano has been designed for verity of LED related applications. The shield provides accurate LED current sink to regulate LED current in a string of LEDs. The LED current is mirrored and the current flowing from the RSET is set by PR1. On board 2W X 3 LED are used for testing purposes.
