A weathervane turns with the wind direction. The base of the weathervane is connected to a rotary potentiometer without stops, that is, the potentiometer turns from o \(\Omega\) to \(10 \mathrm{k} \Omega\) linearly clockwise, but jumps to \(0 \Omega\) after the maximum resistance is reached and would continue toward \(10 \mathrm{k} \Omega\) if the weathervane continues to rotate clockwise. The need is to output the voltage from the potentiometer to comparators that will light 2-VDC LEDs. Each LED will correspond to a wind direction, N, NE, E, \(\mathrm{SE}\), etc. Set North at \(1 \mathrm{~V}\) (hence it should always be ON as long as the system is \(\mathrm{ON}\) ) and \(\mathrm{NW}\) at \(8 \mathrm{~V}\). As the vane turns clockwise from \(\mathrm{N}\) to \(\mathrm{NW}\), additional LEDs come on. If the vane turns counterclockwise, the LEDs go off as it turns. You have available a 15 -VDC supply.
