FantomXR Posted November 19, 2019 Report Share Posted November 19, 2019 Hey people, I was looking for a way to detect, if an encoder (with metal shaft of course) is touched. Since NG itself doesn't support such touchsensors I was searching for an IC. And I found it:https://www.mouser.de/ProductDetail/Microchip-Technology/AT42QT1010-TSHR?qs=xbJoyvfFV%2F%252BFK88JVR2efg%3D%3D I've added a 22nF cap between SNS and SNSK and put a 10k resistor right before the encoder. It works great! As soon as I touch the encoder, the "OUT" goes high and if I release it it goes back low. You just have to connect that to an inputpin of an HC165 and you are done.

Antichambre Posted November 19, 2019 Report Share Posted November 19, 2019 Great! Did you look for and find some knob to go with it? Best Bruno Quote Link to comment Share on other sites More sharing options...
FantomXR Posted November 19, 2019 Author Report Share Posted November 19, 2019 Any knob made from metal will do. Even a plastic knob should do. But you'd need to increase the cap between SNS and SNSK to make it more sensible. I use knobs from Kobler here in Germany. Quote Link to comment Share on other sites More sharing options...
