NLSF595 - Tri-Color LED Driver - Arduino Shift Register

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
