FYP 2 Week 10

This week I still test the circuit on breadboard to achieve a much better results. For my project, it has 3 states. The first state is when the fan is not moving if the temperature sensor sense the temperature is below or equal 24°C. The second state is when the temperature is above 24°C, the fan then will move at the normal speed. The third state is when the temperature is above 37°C. If this occurred,  the fan will move at its maximum speed.

Here is the results from the serial monitor that you can see from the Arduino 1.0.3 software:

Fan started with the normal speed when it doesn't reach the certain temperature.

When the temperature sensor detected the temperature has risen to a certain degree, the fan will increase its speed to maximum.

If the temperature dropped from that certain degree, then the fan will return to its normal speed.

Below is videos of the results of this project on breadboard:

This is video for the first state to the second state (fan turn off -> fan turn on at normal speed)

And this is video for the second state to the third state (fan turn on at normal speed -> fan at maximum speed)
