Please help I am A noob At computer and Arduino
Sorry for my english(Not my first language)

Is your system (operating system) 64 bit? I had problems with that and had to get drivers from the FTDI page for the USB connection

nope 32 bit!

Hi,

There's a webpage on Arduino Getting Started

Did you try it, and at which stage are you now at?

I cannot find arduino on device manager..No reaction on computer when arduino is plugged in(win 7)

Bump.
