Inspiration

Sitting in bed during COVID19 quarantine and being too lazy to get up to adjust the air conditioning.

What it does

Our project features a potentiometer, DC motor, and a TMP36 temperature sensor. In this case, the DC motor represents a fan. Users can manually adjust the potentiometer to adjust the speed of the motor, representative of the speed of rotation of a fan. As the temperature of the room changes in response to the rotation of the fan, the temperature sensor outputs the reading, in degrees Celsius, onto the serial monitor. In the current simulation, the temperature values are printing in the opposite way they should be (they are indicating higher temps when the fan is spinning faster rather than showing the actual drop in temperature). This is because Tinkercad does not allow us to add the fan attachment so the “environment” in the program does not have a temperature change to read. If this was done in person, the sensor would be reading the room and printing appropriate values (a decrease in temperature corresponding to an increase in the fan’s speed).
