Hi, my lecturer has given me an LT3092 IC to connect to an Arduino Uno R3 board with some resistors to get an output on my laptop but I am not really sure how to do it. I'm not sure where to connect it to, Analog or Digital? Hope I can get help 
have a look at the LT3092 datasheets users guides etc
could you use a digitally-programmable-potentiometer controlled by an Arduino as Rset ?
