Use
To simplify the mechanical aspects of this design, we are using a simple
linkage that translates the move of the servo arm directly to the manual lever
of the damper.
The sensor device can be placed anywhere in the room since it is a
standalone device. This is helpful so that it can be placed away from air
registers or windows that might inadvertently affect sensor readings for the
purpose of regulating room temperature.
The Huzzah is powered with a standard micro-USB DC power supply—the
same kind that power many of today's smartphones and other portable
electronics. The weather shield stack is powered with a 5V DC barrel jack
power supply. Power supplies that provide sufficient power are included in the
project shopping cart for your convenience.
Of course, this project could be altered to fit any number of scenarios or
system configurations. For example, instead of opening and closing dampers,
the system could be repurposed to open and close window blinds based on
temperature. Or this could be done in addition to the damper control by simply
adding a second control unit. The possibilities are endless.
