Unformatted text preview: a variable resistor placed 1875 mm below the track at the zero position (see the diagram). The shaft is spring loaded so the cable is always wound tightly. The shaft will turn exactly one revolution for each ten centimeters of cable unwound. The circuit should use a 10 V, 16-bit ADC, H ADC (10 V , 16) . Try to use the full range of the ADC input by eﬃcient use of the variable resistor. 2500 1875 Track Object Variable Resistor Shaft Object Motion • As part of the design determine the number of turns from minimum to maximum position, and choose a maximum resistance. • Find a model function for the variable resistor (rotation to resistance) and ﬁnd the mapping from object position to shaft rotation. • Show a schematic of the circuit showing all component and supply values. • Show pseudocode or C code for the interface routine....
