I am trying to make the front of the built-in fridge and freezer tilt via capacitive switches.
I have tried using a TTP223 and an AT42QT1011.
But I have a problem with the self-tilting.
To make it work through the furniture board, I added a wire and a piece of laminate from a single-sided PCB to the PAD field.
The principle is as follows:
When the front is touched, the AT42QT1011 sends a high state, registered by the ESP32, and a script is executed that triggers two relays that change polarity, which activates an actuator that tilts the front. This would all work very nicely if it weren't for the fact that I have a false 'touch' every so often which opens the front.
I think the reason may be that the fridge is metal and there is about 4mm from the front to the fridge.
Do you have any ideas on how to eliminate the false 'touches'?
For the time being, the fridge is not even switched on and no one is in the room. I have no idea what to do anymore.
