The first tests

After talking with the teacher we knew that he is thinking about a temperature variation of about 2° in steps op 0,1°.

So this is normally possible with a small E10 light bulb of 3-5 Watt.

Yester we have done a first test with the Labjack. This was made a small program
in Visual Basic to turn on and off a LED on a digital output of the Labjack.
The reason of this test was that we want be sure that we can communicate from software to Labjack and turn on and off an output.
After installation of the driver and including the ".dll" we had the first test working.
This is our program code :
----------------------------------
Public Class Form1

    Private Sub Btn_aan_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Btn_aan.Click
        lj.LabJack.EDigitalOut(-1, 0, 0, 0, 1)

    End Sub

    Private Sub Btn_uit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Btn_uit.Click
        lj.LabJack.EDigitalOut(-1, 0, 0, 0, 0)

    End Sub
End Class
----------------------------------

And this is how looks the frame with the buttons:

Also yesterday, we have removed 4 fans of old devices. So now we need only 1 more.
Today we have done the first tests with a fan and a small light bulb. We are now quite sure that it is possible to heat about 2° with a small light bulb. But the Labjack U12 doesn't support PWM, so we have to search for something else. We are now testing with a circuit that makes a PWM signal with a analog output of the Labjack.
