Hi all,
I have an array of N switches . Initially all are OFF.
Somebody turns them ON in some order. It is possible that more
switches are turned ON in the same moment.
I need a device which shows me the order in which the switches were
turned ON. For instance the device should give me: 4,3,1,5,2 (this is
the order in which the switches were turned ON).
The way in which the output is shown in not important. It must be
simple to read (by a human, computer, etc).
It is important that the device is able to handle the turned ON (in
the same moment) of the multiple switches.
thanks,
Laura |
