I'm new to Arduino and I could use some help figuring out what to buy. I have a simple project where I need to log the date and time every time a button is pushed. Ideally, I'd like to create a text file on a USB stick where a new line is written each time the button is pushed. It would look something like:
20101214_150522 20101214_150548 20101214_150633
if the button were pushed on Dec. 12, 2010 at 3:05:22 pm, 3:05:48 pm, and 3:06:33 pm. Exactly what hardware do I need to buy to make this happen? I have plenty of resistors, buttons, and simple circuit components on hand. The only real constraints are that I'd like to keep this low-cost and low-power.
Thanks in advance!
