Esplora Joystick Mouse
|
|
|
|
This sketch shows you how to read the joystick and use it to control the movement
|
|
of the cursor on your computer. You're making your Esplora into a mouse!
|
|
|
|
WARNING: this sketch will take over your mouse movement. If you lose control
|
|
of your mouse do the following:
|
|
1) unplug the Esplora.
|
|
2) open the EsploraBlink sketch
|
|
3) hold the reset button down while plugging your Esplora back in
|
|
4) while holding reset, click "Upload"
|
|
5) when you see the message "Done compiling", release the reset button.
|
|
|
|
This will stop your Esplora from controlling your mouse while you upload a sketch
|
|
that doesn't take control of the mouse.
