Hey all,

I'm sending a signal to my Arduino Uno board via a Win32 C++ program. Would anyone know how I can check the time from when the signal is sent to the time the board receives it?

Thank You.

Let the Arduino echo the signal and let the C++ program measure the time, and divide it by two That should give you a fair approximation of the time needed.

This works in theory for any protocol you are using. It is the basis of the NTP protocol to synchronize computers time.
