I bought a few
HTTM Capacitive touch switch button module, just because they looked cool
Got them today and connected +5V and GND to one. Then I measured the output voltage. I thought this would give either 0 og ~5V out, but no. It give 3.9 or 4.7 v out.
I search the big internet to find any good solution on how to "convert" the output to logic 1 or 0, but have not found anything. Perhaps some gurus in here have any suggestions?
