To control the rotation speed of a dc motor with temperature, we use a TM35 temperature sensor, a DC motor and a Nucleo-F411RE development board. The DC motor speed will increase according to the temperature change to higher and decrease on opposite. We define three threshold temperatures. One of them should be below room temperature, second one should be close to room temperature and the last one should be above room temperature. When the lowest one is passed the dc motor should be rotated at v1 rpm. When the middle one is passed the dc motor should be rotated at v2 rpm. When the  highest one is passed the dc motor should be rotated at v3 rpm.

The values of v1, v2 and v3 can be chosen arbitrarily so that v1 < v2 < v3.

 

Design an experimental setup to control the speed of the dc motor with the LM35 sensor. Draw the connection diagram of this setup.
