I kept all the cut out pieces in order to change the design as I need it by putting them back in place.<br><br> | I kept all the cut out pieces in order to change the design as I need it by putting them back in place.<br><br> | ||

The bottom part features eight and the upper part features six „circuit lanes“ that are located in a way so that they form a kind of matrix-grid when they are put on top of each other. <br> | The bottom part features eight and the upper part features six „circuit lanes“ that are located in a way so that they form a kind of matrix-grid when they are put on top of each other. <br> | ||

I first planned to use a resistor ladder for the Analog input pin of the arduino in order to minimize the amount of pins being used.<br><br> | I first planned to use a resistor ladder for the Analog input pin of the arduino in order to minimize the amount of pins being used.<br><br> | ||

As this did not work out (too many delays in the code, too slow, a lot of noise) I changed the design by attaching a separate wire to each of the eight „circuit lanes“ that go to the Arduinos digital input.<br> | As this did not work out (too many delays in the code, too slow, a lot of noise) I changed the design by attaching a separate wire to each of the eight „circuit lanes“ that go to the Arduinos digital input.<br> | ||
