[Testing] OLPC testing activities

[James Cameron]

Measure activity can only measure light and temperature using an
external device attached to the microphone socket.  If you don't have
those devices, it is not possible for you to test these features.

http://wiki.laptop.org/go/Measure has some old information about
transducers and attachments.

The current version of Measure activity provides a Sensors tab with
Resistance Sensor and Voltage Sensor modes.  In these modes, the
microphone input works by converting the DC voltage level into digital
data for display.
