Installing the Arduino

Use 3 screws through the holes in the Arduino as shown. The fourth screw hole on the Arduino may be blocked by the header pins. Don't worry if the fourth screw doesn't fit, 3 screws will be enough.Twist the standoffs onto the screws.

Screw the Arduino to the frame. Tighten the screws barely enough to hold the Arduino down. The holes are plastic and can be easily stripped if overtightened.

If the holes do get stripped, Hot glue can be substituted to hold the Arduino in place. Apply the hot glue to the screws and standoffs and place the screw through the holes.
