down, left, and right.
Each press of this button will change the direction of the numbers projecting
onto the ceiling by a quarter turn.
Project temperature only
This clock is designed to continually alternate between time and outdoor
temperature. This cannot be adjusted.

intensity feature that will choose intensity levels or turn the projection off.
