Serial Communication Exercises – Zaeem

Exercise 1

Sketch:

Arduino Code:

void setup() {
  Serial.begin(9600);
  pinMode(5, OUTPUT);
  while (Serial.available() <= 0) {
    Serial.println("0,0"); // send a starting message
    delay(300);              // wait 1/3 second
  }
}

void loop() {
  while (Serial.available() > 0) {
    // read the incoming byte:
   int inByte = Serial.read();
   analogWrite(5, inByte);

    int sensorValue = analogRead(A0);
    Serial.print(sensorValue);
    Serial.println();
  }
}

Exercise 2

Sketch:

Arduino Code:

void setup() {
  Serial.begin(9600);
  pinMode(5, OUTPUT);
  while (Serial.available() <= 0) {
    Serial.println("0,0"); // send a starting message
    delay(300);              // wait 1/3 second
  }
}

void loop() {
  while (Serial.available() > 0) {
    // read the incoming byte:
   int inByte = Serial.read();
   int brightness = inByte * 50;
   analogWrite(5, brightness);
  }
}
