Lab 11 - Serial IO

CLASSWORK:
POT reading converted to Percentage
//Simple Serial Printing Test with a Potentiometer 
const int POT=0; //Pot on analog pin 0 
void setup() { 
 Serial.begin(9600); //Start serial port with baud = 9600 
} void loop() { 
 int val = analogRead(POT); //Read potentiometer 
 int per = map(val, 0, 1023, 0, 100); //Convert to percentage
 Serial.print("Analog Reading: "); 
 Serial.print(val); //Print raw analog value 
 Serial.print(" Percentage: "); 
 Serial.print(per); //Print percentage analog value   Serial.println("%"); //Print % sign and newline 
 delay(1000); //Wait 1 second, then repeat 
} 

Serial Printing a Potentiometer Data Table
//Tabular serial printing test with a potentiometer 
const int POT=0; //Pot on analog pin 0 
void setup() 
{ 
 Serial.begin(9600); //Start Serial Port with Baud = 9600 
} 
void loop() { 
 Serial.println("\nAnalog Pin\tRaw Value\tPercentage");
 Serial.println("------------------------------------------"); 
 for (int i = 0; i < 10; i++) { 
 int val = analogRead(POT); //Read potentiometer 
 int per = map(val, 0, 1023, 0, 100); //Convert to percentage   Serial.print("A0\t\t"); 
 Serial.print(val); 
 Serial.print("\t\t"); 
 Serial.print(per); //Print percentage analog value   Serial.println("%"); //Print % sign and newline 
 delay(1000); //Wait 1 second, then repeat 
 } 
}

Echo Serial Inputs to the Serial Output Space
//Echo every character char data; //Holds incoming character 
void setup() { 
 Serial.begin(9600); //Serial Port at 9600 baud 
} 
void loop() { 
 //Only print when data is received 
 if (Serial.available() > 0)  { 
 data = Serial.read(); //Read byte of data 
 Serial.print(data); //Print byte of data 
 } 
} 

HOMEWORK:
Serial Input RGB values to light up RGB LED
//Sending Multiple Variables at Once
//Define LED pins
const int RED =11;
const int GREEN =10;
const int BLUE =9;
//Variables for RGB levels
int rval = 0;
int gval = 0;
int bval = 0;
void setup()
{
 Serial.begin(9600); //Serial Port at 9600 baud
 //Set pins as outputs
 pinMode(RED, OUTPUT);
 pinMode(GREEN, OUTPUT);
 pinMode(BLUE, OUTPUT);
}
void loop()
{
 //Keep working as long as data is in the buffer
 while (Serial.available() > 0)
{
 rval = Serial.parseInt(); //First valid integer
 gval = Serial.parseInt(); //Second valid integer
 bval = Serial.parseInt(); //Third valid integer
 if (Serial.read() == '\n') //Done transmitting
 {
 //set LED
 analogWrite(RED, rval);
 analogWrite(GREEN, gval);
 analogWrite(BLUE, bval);
 }
 }
