Demo of a simple combination of parts from Electric Dollar Store:
|
||
|
|
|
||
|
|
* MAGNET - 3-axis magnetometer
|
||
|
|
* LED - RGB LED
|
||
|
|
|
||
|
|
This demo takes the compass direction, and uses it to set the LED's
|
||
|
|
color. So as you move the module around, the color changes according to
|
||
|
|
its direction. There is a direction that is pure red, another that is
|
||
|
|
pure green, etc.
