Arduino Tips & Tricks Chapter 2 – Flash an External LED

This is the second chapter in a series of chapters that will teach you the basics of Arduino programming. I take you through all the basics and at the end of each chapter is a "next steps" section with a link to the project hardware and code loaded into Tinkercad.com circuits where you can simulate the project on your computer and also make changes to the code if you want.

This chapter shows you how to control an external LED.
