Esplora Accelerometer
3+
4+
This sketch shows you how to read the values from the accelerometer.
5+
To see it in action, open the serial monitor and tilt the board. You'll see
6+
the accelerometer values for each axis change when you tilt the board
7+
on that axis.

This sketch shows you how to read the joystick and use it to control the movement

6+
7+
WARNING: this sketch will take over your mouse movement. If you lose control
8+
of your mouse do the following:
9+
1) unplug the Esplora.
10+
2) open the EsploraBlink sketch
11+
3) hold the reset button down while plugging your Esplora back in
12+
4) while holding reset, click "Upload"
13+
5) when you see the message "Done compiling", release the reset button.
14+
15+
This will stop your Esplora from controlling your mouse while you upload a sketch
16+
that doesn't take control of the mouse.

Esplora Led calibration
3+
4+
This sketch shows you how to read and calibrate the light sensor.
5+
Because light levels vary from one location to another, you need to calibrate the
6+
sensor for each location. To do this, you read the sensor for a few seconds,
7+
and save the highest and lowest readings as maximum and minimum.
8+
Then, when you're using the sensor's reading (for example, to set the brightness
9+
of the LED), you map the sensor's reading to a range between the minimum
10+
and the maximum.
