After experimenting with the touch sensors since their arrival, we found it to be quite interesting and fun to play around. in the photos below it is illustrated when the LED goes on as it is touched, and going off as the finger moves away from it and then back on as it is touched again.
The code for this will be pasted here by Laurence.
As for the model, it has now progessed to fit each individual sensor (six of them) as keys on the keyboard.
As seen in the holes below, this is left vacant on purpose to allow the wires to pass through from male to female. From the arduino board, to the touch sensors.
The holes are where the LED bulbs will shine their specific light accordingly.
