2 | Esplora Joystick Mouse
|

|
---|
4 | This sketch shows you how to read the joystick and use it to control the movement
|
---|
5 | of the cursor on your computer. You're making your Esplora into a mouse!
|
---|
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.
