Tugas Pendahuluan Modul 3
1. Kondisi
[Kembali]
Buatlah led menyala ketika potensiometer 0% dan led padam ketika potensiometer 100%
2. Rangkaian Simulasi [Kembali]
 |
| LED menyala ketika kondisi potensiometer 0% |
 |
| LED mati ketika kondisi potensiometer 100% |
3. Flowchart
4. Listing Program [Kembali]
//MASTER
#include <Wire.h>
#define MASTER_ADDR 9
//0-127 alamat 12c
int analogPin = 0;
int val = 0;//dari mapping
void setup() {
Wire.begin();//siap mengirimkan data
}
void loop() {
delay(50);
val = map(analogRead(analogPin), 0, 1023, 255, 1);//pembacaan potensiometer, prubahan poten, proses adc
//0-123adc
//1-255pwm
Wire.beginTransmission(MASTER_ADDR);//memulai transmisi
Wire.write(val);//dituliaskan sesuai dg value y didapatkan
Wire.endTransmission();//berhenti
}
//SLAVE
#include <Wire.h>
#define SLAVE_ADDR 9
int LED = 13;
int rd;
int br;
void setup() {
pinMode(LED, OUTPUT);
Wire.begin(SLAVE_ADDR);
Wire.onReceive(receiveEvent);
}
void receiveEvent() {
rd = Wire.read();
}
void loop() {
delay(50);
br = map(rd, 1, 255, 100, 2000);
if (br == 2000){
delay(1000);
digitalWrite(LED, HIGH);
}else{
delay(1000);
digitalWrite(LED, LOW);
}
}
