Write an Arduino program to read the state of PK2, output this state on PDO, and output the complement of this state on PE3. Write the program to minimize the time delay between a change on PK2 reflecting onto PDO and PE3. Attach a button to PK2, and an LED (with a series resistor) to PDO. 1. Use an oscilloscope to measure the propagation delay between PK2 and PDO. 2. Use an oscilloscope to show the difference between PDO and PE3 Write an Arduino program to read the state of PK2, output this state on PDO, and output the complement of this state on PE3.
