# This is the library for Hover.
|
||
|
|
#
|
||
|
|
# Hover is a development kit that lets you control your hardware projects in a whole new way.
|
||
|
|
# Wave goodbye to physical buttons. Hover detects hand movements in the air for touch-less interaction.
|
||
|
|
# It also features five touch-sensitive regions for even more options.
|
||
|
|
# Hover uses I2C and 2 digital pins. It is compatible with Arduino, Raspberry Pi and more.
|
||
|
|
#
|
||
|
|
# Hover can be purchased here: http://www.hoverlabs.co
