So I'm embarking on a new and (for me) rather ambitious project. The basic idea is that I am building a round table composed of multiple concentric circles, which will spin independently when triggered by capacitive touch sensors being activated.
Here is a vimeo video of the idea to help visualize it - Video of concept
The basic concept is that the table is a historical timeline that can only be aligned and 'viewed' when multiple people are seated at the table and have their hands on it.
The engineering and design side I have sorted, basically there will just be single stepper motor that drives the inner circle and forces the other circles to move with it.
My questions are really about how to combine multiple capacitive touch sensors in order to trigger the stepper motors movement, and whether anyone knew of any helpful projects that may assist me? I currently plan to either have the sensors (just foil or copper) hidden under a thing veneer with hand shaped decals, or have copper plates built into the table that you place your hands on.
The ones I have currently been looking at to try and piece together are
https://www.arduino.cc/en/Tutorial/StepperUnipolar (for controlling the stepper motor in two directions)
and then the capacitive sensing portion of this e-book that talks about controlling a servo with a capacitive touch sensor
I figure I can couple these two pieces of code together to form the basic trigger, but I still don't understand how to combine the multiple sensor inputs so that the table only moves if all 6 capacative sensors are receiving readings.
Any hints? Much appreciated!!!!
