5a.) Assume you are measuring a voltage on the analog input pin A0 of your Arduino. You would like to display the measured voltage on the serial monitor. In the code below, write in the appropriate command to measure the voltage at pin a0 and display measured voltage in [v]. Write these commands below the read and print comments below. void setup() { // initialize serial communication at 9600 bits per second: Serial.begin(9600); } // the loop routine runs over and over again forever: void loop() { | // read the input on analog pin 0: // print out the value you read: }

Exercise III: Processing interrupts caused by changes on pins PB4-PB7: Program "intportb.asm" illustrates how interrupt can be employed for indicating changes on pins RB4- RB7. Upon pushing any of the buttons, program enters the interrupt routine and determines which pin caused an interrupt. The figure bellow represents the wiring system of the PIC, the push buttons and the LEDs.
