Description: The AVR Stick is a simple data logging device that instantiates itself as an HID keyboard and reports the voltages, along with a 'timestamp,' from two pins on an ATtiny85. The device uses open source firmware availabe from Objective Development ( http://www.obdev.at/vusb/ ) called V-USB to implement the USB 1.1 standard. The code that runs the application was based on the EasyLogger example application from Objective development. The default firmware runs simply enough: plug it in to a USB port on your computer, after the computer recognizes the device as a keyboard it will automatically start reporting the voltages. To get a series of measurements, open up a text or spreadsheet editor and plug the AVR stick in. The AVR Stick will automatically start inputting the voltage values to whatever program is active on the computer.
