We don't have a picture of the motor hooked up but the second major problem we mentioned in the video. The motor we originally were going to use wouldn't work with our relay and op-amp configuration and when ever the circuit would power the motor we assumed the motor drew to much current and would cause the circuit to stop. Making us have to heat up the temp sensor again to restart it only for it to stop again. After trying our the motor used in figure 1 the video the whole circuit would work as intended.
