Originally we were considering using a servo to move the sculpture, however, after researching this method, we discovered that not only will the servo not do the amount of rotations that we need (3) that to gear it to make it rotate the desired amount we will lose some torque. After using the sculpture a few times I do not believe I will get the forces required to move it by gearing the servo. Because of this we will look into using a stepper motor.
We also discovered that the thermistor can have unreliable readings ranging between 4 degrees C. Because of this we will need to ensure that we take a reading over 5-10 seconds and then use the average temperature. We will also be making a sound using a piezo buzzer whenever the sculpture moves.
