In this chapter you will learn about some of the more advanced features of the Photon and Core.
Although the Tinker App is a very convenient way of setting up a new Photon/Core, it is not the only way of telling a new device your WiFi credentials. The USB socket on a Photon or Core is not just for supplying the device with power; it can also be used to communicate with your computer over USB.
You can pass WiFi credentials to your Photon/Core using the USB connection and a serial communication program. If you have a Mac or Linux computer, then you already have a built-in utility (called screen) for this kind of serial communication over USB.
