3 LCD display which displays a number from 0-999 depending on the resistance change on a variable resistor from a wheatstone bridge. The value should show the highest change (ie the maximum resistance change on the variable resistor) . The LCD display will be reset to 000 when a reset button is pressed. Power supply will be a DC battery, please indicate batteries required for the circuit.
This needs to be as cheap as possible to keep manufacturing costs down.
If the prototype is okay I will need two more different designs which are slightly more complicated
