Although some Arduino boards such as the Leonardo (and compatibles such as our LeoStick) can emulate a USB keyboard for quick data transmission back to a PC, this hasn't been the case for Uno and compatible boards with the ATmega328P microcontroller. However with an Arduino library by Philip Lindsay and a demonstration by Ray Burnette it's easy to have your Arduino Uno or compatible send data back to a PC.
Ray's example shows how to log six digital and six analogue Arduino pins at the same time, and sends the data back to Microsoft Excel for display and analysis. At first thought this process seems complex, but nothing could be further from the truth as both the required external circutry and Arduno demosntration sketch are provided.
So to get started, check out Ray's project page. And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
If you need to add external hardware or devices to your next Arduino project, you'll need a protoshield to mount the external circuitry. In doing so, consider our range of ProtoShields. From the tiny LeoStick to the Mega we have a wide range to suit your application.
