Story

If you want to to try some basic Internet of Things project, I think this project will match for you.

On April 2019, I got a task from my lecturer in microcontroller subject. My team and I then got this idea.

This idea is so simple. We want to control our home lamp remotely from our smartphone. There are several method to make this idea come true. We can control the lamp using Bluetooth, or using Internet network. Then we decided to use the Internet network trough Android apps to control the lamp.

For the Android apps, we use Blynk. It's so simple to configure, so we decided to use it.

That's all for the story, happy learning!

Code

Code

#include <BlynkSimpleEsp8266.h>
#include <ESP8266WiFi.h>
char auth[] = ""; // Change with your Blynk Auth Code
char ssid[] = ""; // Use your WIFI SSID 
char pass[] = ""; // password

const int relay1 = 14;
const int relay2 = 12;
const int relay3 = 13;
const int relay4 = 15;

int ledPin = 5;
 
void setup(){
  Blynk.begin(auth, ssid, pass);
  pinMode (relay1, OUTPUT);
  pinMode (relay2, OUTPUT);
  pinMode (relay3, OUTPUT);
  pinMode (relay4, OUTPUT);
  
  digitalWrite(relay1, LOW);
  digitalWrite(relay2, LOW);
  digitalWrite(relay3, LOW);
  digitalWrite(relay4, LOW);
}

void loop() {
  Blynk.run();  
}
