This is the IC that I have INA128P. Look at the schematic on the first page. 1. Connect S- to pin 2 of the INA128, connect S+ to pin 3 of the INA128. 2. If you have a bread board connect the netduino +5v and ground pin to the power rails on the bread board.3. Connect E- and E+ to the breadboards power rails. 4. Connect pin 7 on the INA128 to the +5v rail.5. Connect pin 4 and pin 5 of the INA128 to the ground rail.6. Either use a resistor for the gain you want or do what I did and use a pot as a variable resistor. Use a multi meter to determine which two pins of the pot will show a resistance change when you turn the pot and connect those to pins 1 and 8 of the INA128.7. Connect pin 6 of the INA128 to the analog pin of the netduino.
