A simple sketch was made in CAD to virtually measure and locate the lights in preparation for the circuit board layout. The lights were first arranged so they had an even distribution across the entire face but the lights near the cross-member would have been less visible. The distribution was changed to have equal distribution in each half as divided by the cross-member.
A device was created in the electrical program for the ISD1820PY sound recorder module. This reflected the 14pin PDIP package and included pin names. Five instances of the recorder module were put into the schematic and wired to the Arduino. Some pins were grounded to keep them inactive but this configuration should be tested with the demo board. The speaker terminals still need to be wired and given a volume control pot.
