Challenge 3: Fun Stuff to Know

Abstract

Are you starting to get more comfortable inserting wires into a breadboard and connecting the Arduino Uno to your computer to upload a sketch? We hope so. The folks who design the Arduino microcontrollers had many goals when they were developing the device, and one of those was to make it as simple as possible for non-technical people to build things. You don’t necessarily need to know how a resistor works or how its chemical makeup makes it do what it does. You don’t need to understand why an LED only works when inserted in the breadboard one way and won’t work when inserted the other way. These are things you can find out about later, with some extra research and reading, should you decide you want a deeper understanding of electronics.
