event-triggered data logger

Hello,
I need a cheap way of recording the time at which a button is pressed and
then transfer the time stamps recorded to a computer in a format readable by Excel.
I have been looking for a similar project because I doubt this is a novel idea.
However, all the data logger project I've found seem to record data at fixed intervals
instead of whenever a certain event occurs (e.g. the closing of a switch).
Before I spend time reinventing the wheel, would you mind letting me know if you've come across such project?
Thank you very much. Pascal.

well projects on internet are always for general requirements. whenever you have specific requirement you will hardly find anything over net

Regarding your requirement, i suggest you use the same logger project, just read data when switch is pressed. if you want to have a timestamp use RTC with controller and send along with data.

OK thank you very much. You probably just saved me a lot of time continuing to look for something that doesn't exist. I'll get started on it. Cheers, Pascal

you're welcome there are datalogger projects available in download section that can help you get started faster with your project make good use of them.

Thanks for the suggestion. I see a couple of codes that will do fine.
And this actually answers another question: I was still debating between 8051, AVR, or PIC and considering the amount of code available for 8051 I think I will go down that route. Would you have any comment about that? i.e. would another family between a better choice?
By the way, the tutorials in the "download" section are also a great resource, I had only found the ones in the "tutorials" section so far. Thank you for this very useful site. Cheers, Pascal
