[title]Electronic switch by voltage from IR Light Barrier[/title]

This class reads in a digital value of a connected voltage. If the input voltage is high (3V - 30.3V), a 0 is read at the input of the extender module. This is caused by a circuit to galvanicly separate the external voltage from the extender voltage.
I used Velleman’s IR Light Barrier as the source. Normally the output is a zoomer, but I took the output signal instead an connected it indirectly to the extender module.
The advantage of this mix of hard- and software is that you can simulate a switch by a power source.
