How would i set up the board so that I could have a hscrollbar that has a slider that moves in real time in relation to the voltage connected to analog channel one

thanks

Here is a code snippet how to do it in Visual Basic 2008:

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick VScrollBar1.Value = ReadAnalogChannel(1) End Sub

Do you get any reading when running the original demo software (.EXE) from the CD or with any other downloaded from here: velleman.eu/distributor/supp … code=K8055

Connect the voltage between the analog input and GND.
