2015-01-28 (W) Color/Touch + Sound

Testing the sound modules started by gathering the modules and a power supply. The power supply was capable of outputting 3.3VDC and 5.0VDC. Both modules were given 3.3V and the same results were replicated from the last test where the first module acted faulty but the second module operated as expected. To test the functions of the chips and the board the chips (ISD1820PY) were swapped. The fault was found on the first board since both chips performed as expected in the second board. This also suggested the first chip was not damaged by the 5.0V. To test this the second board had 5.0V applied and all functions tested well. A video was made demonstrating the operation of the board at 5.0V.
