Exercise 1

Arduino:

void setup() {
  Serial.begin(9600);
  while (Serial.available() <= 0) {
    Serial.println("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 sensorValue = analogRead(A0);
    Serial.print(sensorValue);
    Serial.println();
  }

Exercise 2:

void setup() {
  Serial.begin(9600);
  while (Serial.available() <= 0) {
    Serial.println("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();
     // brightness = map(inByte, 0, 1023, 0, 255);
    analogWrite(5, inByte);
    Serial.println(inByte);
  }

Exercise 3:

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 onoff = Serial.read();
   analogWrite(5, onoff);
    int sensorValue = analogRead(A0);
    Serial.print(sensorValue);
    Serial.println();
  }
