Hi All I am very new to NetDuino and have not bought my first board yet, since I want to do design my rig first to avoid wasting money... And I need some advice on what to buy. My NetDuio rig needs to be able to control the resistance of 29 differen wires (from another rig that I will build not using NetDuino). My question is: what kind of components should i get besides the NetDuino Plus board to be able to do this, and what parts of the Duino board can handle increasing the resistance in 1 of the 29 wires/circuit at a time. Please remember to speeeeak slooooowly when providing feedback. I am no electronic engeneer Tnx in advance for any feedback.

Tnx in advance for any feedback.

For something like this the easiest way is likely to use a digital Potentiometer, which is essentially just a variable resistor. A part like the DS1806 from Maxim should work fine, and there is already a Netduino driver for it.
