# Install your Device

MailBox System & CellPhone

Install your device in your assigned teachers box 

What to turn in: 1 photograph showing system design with light on (before installation) and 1 photograph of installed device (light may be on or off depending on your choice) the picture should be "inside the box" so I can see how actually installed.

**TIP**:Because each group has at least 2 assigned teachers please make sure you have images from both installations
