First Breadboard Circuit

Here is a close-up of the circuit you will build above a diagram called a schematic.  A schematic has information about how the parts are electrically connected, but the details of how that circuit is built on a breadboard is up to the person building the circuit.  In other words, the circuit you see plugged into the breadboard is just one of many possible “correct” ways to build it.  

This activity starts with a simple light circuit.  It’s a lot like the lights on your micro:bit, except you can pick the color, red, green, or blue.  We’ll start with green. 

If this is your first time building circuits on a breadboard, follow along carefully.  Along the way, you’ll also get to learn about the parts as well as what happens when electric current flows through the circuit.
