First I will blink single LED using Arduino UNO and then I will blink multiple LEDs in Proteus. Today, I am going to share a very Simple Arduino LED Example in Proteus ISIS. We have covered enough Arduino commands in this Arduino Tutorial for Beginners series and now we are ready to create a simple project by interfacing an LED (Light Emitting Diode). Hello friends, I hope all are fine and having fun with your projects.
