First total test

Tuesday was it a big day. The first version of the software was finished so we could test is with the hardware. But this was in a open classroom. But it works very well. 
The software is written in C++ because we started of an example, this was the easiest and quickest way. Joeri did well research in this stadium, because we had no C++ experience.

 

In the movie you can see a fan and a led. In the future will the led be replaced by a bigger lamp. But the led is an indication for the heating element.

When we start up the software we need to push on 'Start' and wait 5 seconds.

This is that we can measure already the temperature and than is the measured value
more correct. The lm35 needs some time to be at the correct value.

When this is done, you can see the measured temperature by the lm35.
And you can give in the temperature you want.
In our test, it was about 23°C in the classroom. So we set that we want a temperature
of 22.8°C.
Than will the fan power on and cool the lm35. When the temperature is below 22.8°C, the led turns on, because it was warmer in the class, the lm35 warms up etc, etc ...
