1.
|
The Finch draws power from this connection and also gets its instructions
a. | Accelerometer | c. | Infrared | b. | USB | d. | LED |
|
|
2.
|
This sensor can detect the direction of gravity, to know how the Finch is
oriented (flat on the ground, upright, etc). It is also possible to detect spikes in acceleration
caused by tapping or shaking the Finch.
a. | Accelerometer | c. | Infrared | b. | USB | d. | LED |
|
|
3.
|
These 2 sensors can detect obstacles in front of the Finch. They do not
provide the distance to an obstacle, but simply register whether an obstacle exists. The sensor
detection range is between 3 and 12 inches.
a. | Accelerometer | c. | Infrared | b. | USB | d. | LED |
|
|
4.
|
This part in the ‘beak’ contains red, green, and blue elements. By
setting the intensity of each element the it can be controlled to make any color.
a. | Accelerometer | c. | Infrared | b. | USB | d. | LED |
|
|
5.
|
How many color settings can you choose from for each color element (red, green
and blue)?
|
|
6.
|

a. | 1 inch per second | c. | 1 inch per minute | b. | 15 inches per second | d. | 15 inches per
minute |
|
|
7.
|
How many motors does the Finch have?
|
|
8.
|
Which kind of sensor are the 2 obstacle detections sensors?
a. | thermistor | d. | computer speaker | b. | photoresistor | e. | infrared | c. | buzzer |
|
|
9.
|

|
|
11.
|
Plays sounds when directed by the Finch. It can talk or play music.
a. | thermistor | d. | computer speaker | b. | photoresistor | e. | infrared | c. | buzzer |
|
|
12.
|
These 2 sensors can easily differentiate sunny and cloudy days and brightness of
various light sources. They allow the Finch to track towards or away from lights.
