Arduino-USB/HID 14-channel data logger

 One of the great things you can do with an Arduino and very little effort is logging data - and most methods generally write data to a microSD card for later analysis by a PC. However we'd like to illustrate another method by Ray Burne - which uses a microcontroller with the Arduino bootloader and external circuitry directly connected to a PC's USB port. The device then reads the status of 14 I/O pins and sends it back to the PC as text - which is made possible by the device acting as a USB keyboard. This opens up more interesting possibilities such as having the data "typed" straight into a spreadsheet or other software.

If you're wanting to reproduce the project above - we've got you covered with our new ATmega328P MCUs with Arduino Uno bootloader:

This is the same Atmel AVR ATmega328P microcontroller used in the official Arduino Uno, as well as our ElevenEtherTenUSBDroid, and other boards. Perfect for building your own Arduino-compatible project directly on a breadboard or on a custom PCB, or for replacing the MCU in an existing board. Comes with the Arduino Uno bootloader pre-installed. Better still, it even has a special label stuck on top with details of the pinout, so you don't even need to look up the datasheet when connecting it up in your project!
