I’ve attached a rough sketch of what I have in mind, but it’s basically a combination of various types of continuous controllers, most of which are touch based.
At the moment, I’m thinking of using a Teensy 3.6, as I’ve used Teensys before, whenever I want to do USB-MIDI.
I have a few questions about doing something like this.
Is the capacitive sensor on the Teensy (or in Arduino-land in general) “analog”? As in, do you get values between 0 through whatever in a continuous manner based on how much skin is touching, or is it simply on/off (touched/untouched)?
If it is analog, do you get the full analog ADC (13-bit) resolution from the touch pins?
Is it possible to have “digital” touch pins that can only tell on/off state (more simply than “analog” pins), by using digital I/O?
Can you touch multiple touch pins at the same time and get separate readings for each? (ala capacitive “multitouch”), or do the values for simultaneously touched pins change based on how many pins are being touched?
Is it possible to multiplex capacitive inputs? As in, how does one go about getting more than 11 capacitive inputs (as per a Teensy 3.6)? What I have in mind uses 52 analog inputs, 44 of which would be touch sensors (though 24 of those could be binary on/off ones). If so, how?
