hiya, my friend and are trying to make a digital dashboard for a truck. i have had quite a bit of experience with VB, but never done any thing with external devices.

this will just need to be a standard app, running on a laptop.

the lapy has a Serial/Com port and USBs (duh') and all of the devices are just standard sensors that need an Ohm reading and 5volts to trip a relay.

the program will have stuff like a speedometer and control over several valves to switch between fuel tanks. (other stuff may come later, but i would just like to start small and build from there.)

all i really need for this is any input you may have on device control/monitoring. i just wanted to give you some context as to what it would be used for, any help would be greatly appreciated, and i will be sure to let you know how it is going.
