SparkFun Capacitive Touch Breakout - AT42QT1011

If you need to add user input without using a button then a capacitive touch interface might be the answer. The AT42QT1010 SparkFun Capacitive Touch Breakout offers a single capacitive touch button with easy-to-use digital I/O pins.The AT42QT1010 is a dedicated single-button capacitive sense chip. The chip handles monitoring a conductive area for touch. As long as a touch (e.g. from a finger) is detected the AT42QT1010 keeps the output line high. Otherwise the line is kept low. You just need to provide a power source (1.8V - 5V) and ground for the AT42QT1010 to work. Additionally a PAD pin is available if you would like to create your own external electrode.Documents:SchematicEagle FilesDatasheet (AT42QT1010)Hookup GuideGitHub
