Kendali Relay 4 Channel via WIFI Local IP Address
Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat mengendalikan relay 4 channel dengan menggunakan wifi local IP Address. jadi alat ini bisa mengendalikan berbagai peralatan rumah tangga atau lampu. untuk lebihjelasnya berikut adalah kodingnya.
1. Program Arduino IDE
#include <ESP8266WiFi.h>
const char* ssid = "hotspotwifiku";
const char* password = "123456789";
int ledPin1 = D1;
int ledPin2 = D2;
int ledPin3 = D3;
int ledPin4 = D4;
WiFiServer server(80);
void setup() {
Serial.begin(9600);
delay(10);
pinMode(ledPin1, OUTPUT);
digitalWrite(ledPin1, HIGH);
pinMode(ledPin2, OUTPUT);
digitalWrite(ledPin2, HIGH);
pinMode(ledPin3, OUTPUT);
digitalWrite(ledPin3, HIGH);
pinMode(ledPin4, OUTPUT);
digitalWrite(ledPin4, HIGH);
// Connect to WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
// Start the server
server.begin();
Serial.println("Server started");
// Print the IP address
Serial.print("Use this URL to connect: ");
Serial.print("http://");
Serial.print(WiFi.localIP());
Serial.println("/");
}
void loop() {
// Check if a client has connected
WiFiClient client = server.available();
if (!client) {
return;
}
// Wait until the client sends some data
Serial.println("new client");
while(!client.available()){
delay(1);
}
// Read the first line of the request
String request = client.readStringUntil('\r');
Serial.println(request);
client.flush();
// Match the request
int value1 = HIGH;
int value2 = HIGH;
int value3 = HIGH;
int value4 = HIGH;
if (request.indexOf("/LED1=ON") != -1) {
digitalWrite(ledPin1, LOW);
value1 = LOW;
}
if (request.indexOf("/LED1=OFF") != -1) {
digitalWrite(ledPin1, HIGH);
value1 = HIGH;
}
if (request.indexOf("/LED2=ON") != -1) {
digitalWrite(ledPin2, LOW);
value2 = LOW;
}
if (request.indexOf("/LED2=OFF") != -1) {
digitalWrite(ledPin2, HIGH);
value2 = HIGH;
}
if (request.indexOf("/LED3=ON") != -1) {
digitalWrite(ledPin3, LOW);
value3 = LOW;
}
if (request.indexOf("/LED3=OFF") != -1) {
digitalWrite(ledPin3, HIGH);
value3 = HIGH;
}
if (request.indexOf("/LED4=ON") != -1) {
digitalWrite(ledPin4, LOW);
value4 = LOW;
}
if (request.indexOf("/LED4=OFF") != -1) {
digitalWrite(ledPin4, HIGH);
value4 = HIGH;
}
// Set ledPin according to the request
//digitalWrite(ledPin, value);
// Return the response
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println(""); // do not forget this one
client.println("<!DOCTYPE HTML>");
client.println("<html>");
client.println("<br><br>");
client.println("<a href=\"/LED1=ON\"\"><button>Turn1 On </button></a>");
client.println("<a href=\"/LED1=OFF\"\"><button>Turn1 Off </button></a><br />");
client.println("<br>");
client.println("<a href=\"/LED2=ON\"\"><button>Turn2 On </button></a>");
client.println("<a href=\"/LED2=OFF\"\"><button>Turn2 Off </button></a><br />");
client.println("<br>");
client.println("<a href=\"/LED3=ON\"\"><button>Turn3 On </button></a>");
client.println("<a href=\"/LED3=OFF\"\"><button>Turn3 Off </button></a><br />");
client.println("<br>");
client.println("<a href=\"/LED4=ON\"\"><button>Turn4 On </button></a>");
client.println("<a href=\"/LED4=OFF\"\"><button>Turn4 Off </button></a><br />");
client.println("</html>");
delay(1);
Serial.println("Client disonnected");
Serial.println("");
}
