I need to push feeds to thingspeak from arduino connected by cable to my laptop

Hello, I am new to thingspeak.
I used to use Xively, and I did not have any problem pushing feeds online. I uploaded Uno firmata to arduino, and used grasshopper; ghowl and firefly.
On thingspeak, I can't push feeds online. What I am trying to do is a simple test of sending photocell data to thingspeak, collected from arduino uno Rs3 which is connected by usb cable to my laptop.
Any help is much appreciated !

Hi. Have you tried Processing?
