Chapter 4. Breadboard
In this chapter, we will deal with attaching some simple external electronics to the Photon or Core, including LEDs and switches. To connect electronic components like LEDs to the Photon/Core, you will use something called a solderless breadboard.
The solderless breadboard (or just breadboard) was invented as a tool for electronics engineers to prototype their designs before committing the projects to a more permanent soldered form. They do, however, make an excellent tool for you to experiment with electronics and make your own projects without the need for any soldering.
Figure 4-1 shows a breadboard with a Spark Core, an LED, and a resistor attached to it. This could also be a Photon.
When you buy a Photon or Core, one ...
