Hallo Gemeinde ,
bin neu hier im Forum und habe vor kurzem angefangen mit Arduino zu arbeiten. Arbeite gerade an einem ESP8266 mit einer 8 Kanal Relay-Modul, was mit dem Code unten ganz gut funktioniert.
Was ich aber gerne ändern möchte ist, wie bekommt man es hin, das ich mit dem Button nur einen Impuls rausgeben kann. Also nicht tasten Button - An, tasten Button - Aus. Bei der Blynk App ist es ja möglich Tasten von Switch auf Push zu stellen.
Hoffe ich habe es verständlich erklärt, ist immer schwierig am Anfang
// Load Wi-Fi library
#include <ESP8266WiFi.h>
// Replace with your network credentials
const char* ssid = "******"; // Input your wifi network name
const char* password = "******"; // Input your wifi password
// Set web server port number to 80
WiFiServer server(80);
// Variable to store the HTTP request
String header;
// Auxiliar variables to store the current output state
String relay1State = "off";
// Assign output variables to GPIO pins
const int relay1 = 5; // GPIO5 D1
void setup() {
Serial.begin(115200);
// Initialize the output variables as outputs
pinMode(relay1, OUTPUT);
// Set outputs to HIGH. relay active LOW
digitalWrite(relay1, HIGH);
// Connect to Wi-Fi network with SSID and password
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
// Print local IP address and start web server
Serial.println("");
Serial.println("WiFi connected.");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
server.begin();
}
void loop() {
WiFiClient client = server.available(); // Listen for incoming clients
if (client) { // If a new client connects,
Serial.println("New Client."); // print a message out in the serial port
String currentLine = ""; // make a String to hold incoming data from the client
while (client.connected()) { // loop while the client's connected
if (client.available()) { // if there's bytes to read from the client,
char c = client.read(); // read a byte, then
Serial.write(c); // print it out the serial monitor
header += c;
if (c == '\n') { // if the byte is a newline character
// if the current line is blank, you got two newline characters in a row.
// that's the end of the client HTTP request, so send a response:
if (currentLine.length() == 0) {
// HTTP headers always start with a response code (e.g. HTTP/1.1 200 OK)
// and a content-type so the client knows what's coming, then a blank line:
client.println("HTTP/1.1 200 OK");
client.println("Content-type:text/html");
client.println("Connection: close");
client.println();
// turns the GPIOs on and off
if (header.indexOf("GET /5/on") >= 0)
{
Serial.println("GPIO 5 on");
relay1State = "on";
digitalWrite(relay1, LOW);
}
else if (header.indexOf("GET /5/off") >= 0)
{
Serial.println("GPIO 5 off");
relay1State = "off";
digitalWrite(relay1, HIGH);
}
// Display the HTML web page
client.println("<!DOCTYPE html><html>");
client.println("<head><meta name=\"viewport\" content=\"width=device-width, initial-scale=1\">");
client.println("<link rel=\"icon\" href=\"data:,\">");
// CSS to style the on/off buttons
// Feel free to change the background-color and font-size attributes to fit your preferences
client.println("<style>html { font-family: Helvetica; display: inline-block; margin: 0px auto; text-align: center;}");
client.println(".button { background-color: #195B6A; border: none; color: white; padding: 12px 24px;");
client.println("text-decoration: none; font-size: 20px; margin: 2px; cursor: pointer;}");
client.println(".button2 {background-color: #77878A;}</style></head>");
// Web Page Heading
client.println("<body><h1>Relaysteuerung</h1>");
// Display current state, and ON/OFF buttons for GPIO 5
client.println("<p>Filter - Satus " + relay1State + "</p>");

// The HTTP response ends with another blank line
client.println();
// Break out of the while loop
break;
} else { // if you got a newline, then clear currentLine
currentLine = "";
}
} else if (c != '\r') { // if you got anything else but a carriage return character,
currentLine += c; // add it to the end of the currentLine
}
