I’m new to arduino and I’m supporting some kids who are exploring them. We want to make a touch lamp-style circuit which will connect to three large pieces of checkerplate aluminium cut into particular shapes. They’ll be free-standing and be approx. 800mm high, resting on wood stands.
Just a note about using capacitive touch sensors, you are more or less using the metallic part of the aluminum as one plate of the capacitor with a larger area you drive the capacitance higher and make a less responsive system. to get around this you could lay some wire or another thin conductor over the top or embed it (be sure not to put it behind something metal!).
The best way to confirm that something would work is to go for it!
