4. Listing Program [kembali]

//MASTER

#include <Wire.h>
#define SLAVE_ADDR 9

int analogPin = 0;
int val = 0;

void setup() {
  Wire.begin();
}

void loop() {
  delay(50);
  val = map(analogRead(analogPin), 0, 1023, 255, 1);

  Wire.beginTransmission(SLAVE_ADDR);
  Wire.write(val);
  Wire.endTransmission();

}
//SLAVE

#include <Wire.h>
#define SLAVE_ADDR 9

int motor = 13;
int rd;
int br;

void setup() {
  pinMode(motor, OUTPUT);
  Wire.begin(SLAVE_ADDR);
  Wire.onReceive(receiveEvent);

  Serial.begin(9600);
  Serial.println("I2C Slave demo");

}

void receiveEvent() {
  rd = Wire.read();
  Serial.println(rd);
}
void loop() {
  delay(50);

  br = map(rd, 1, 255, 100, 2000);

  digitalWrite(motor, HIGH);
  delay(br);
  digitalWrite(motor, LOW);
  delay(br);
}


6. Kondisi [kembali]

Buat rangkaian seperti Percobaan 3. Ganti LED dengan motor DC. Buatlah motor DC berputar berlawanan arah jarum jam. Amati kecepatan saat kondisi potensiometer 0 persen dan 100 persen.
