i've got some troubles with connecting two or more capacitive touch sensors to my arduino mega.
i'm using the Capacitve Sensing Library which works well for one sensor. But as soon as i connect two sensors, the loop seems to slow down and i have to press on both of them to get the loop running properly.
Additionally, the sensors seem to interfere each other, when i press one button, it seems to increase the value of the other one too.
Does anybody have an idea what the reason could be?
