Story

NLFS595 is a serial tri-colour LED driver. You can use the Wokwi Arduino simulator to learn how to interface a tri-colour LED driver to UNO in your next Arduino project.

you will need the following items to complete your Arduino simulator tri-colour LED project

Arduino UNO
Tri-colour LED driver (NLSF595)
Connecting wires
Tri Color LEDs x 2
