Hello all,
I am a chemical researcher looking to find out what the heck is the name of a piece of equipment.
I work all the time with data loggers, some of which are very small and reasonably priced. $50 for four channels logging of incoming voltage, saved to a file that can then be downloaded. What would you call something that did the reverse, that is send out voltages based on an uploaded file? Assuming I a looking for the cheapest possible incarnation, what would the likley cost be?
I am thinking about building a small robot but since any change is command steps will be rare I dont want more computer than is necessary.
