Evening All

Im new to vb.net, in so far as the last time I wrote anything was V6 ! What has happened to it !!!!!

Anyway, my little problem is that I have some buttons on a form that increment the value of an integer. This integer is sent to an arduino via a serial cable.
I dont want the user tho have to press a send button after changing the value, but at the same time I dont want every value the integer holds to be sent ether as the user happily clicks away to reach there desired value.
I was wondering if there is a simple way I can achieve this. Maybe by use of a timer somewhere.

Your thoughts would be very much appreciated.

Thanks
Phil
