Hardware Testing

Today, tests were done to verify the functionality of every pin of each port found in the microprocessor, and every pin turned on successfully indicating that the soldering was not faulty.

The voltage regulators since never before used, were tested in a simple circuit to turn on a LED which would get damaged if given 5 volts. Tests were done with resistors and LED lights. A 3.3V regulator was used to intercept the voltage and output an acceptable amount of voltage that turns the led on as seen in the photos below.
