goedendag
Ik ben nieuw met programeren met esp8266.
heb al wel wat ervaring met arduinos opgedaan en programeer doorgaans meer in delphi (7) en soms wat scripts in python.
Mijn vraag en probleem zijn nu:
Ik heb een 3D geprint brandweer wagentje van 8cm lang en heb daar 2 leds op gemaakt met een wemos D1-mini (van berrybase)
daar het blink programma voor aangepast zodat de leds afwisselend 3x links en dan recht knipperen. dit werkt prima.
Toen heb ik een webserver getest en werk ook prima (led aan uit etc via wifi)
maar nu is mijn vraag hoe kan ik dat knipperen van die 2 leds opnemen in de server loop, zodat na aanzetten via wifi de leds blijven knipperen tot ik ze weer uit schakel ?
Kan iemand me daar verder mee helpen ?
de code die ik geprobeerd heb (werkt voor geen meter uiteraard)
code:
// Load Wi-Fi library
#include <ESP8266WiFi.h>
// Replace with your network credentials
const char* ssid = "XXXXXXXXXXXXXXXX";
const char* password = "XXXXXXXXX";
// 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 output5State = "off";
String output4State = "off";
// Assign output variables to GPIO pins
const int output5 = LED_BUILTIN;
const int output4 = 4;
// Current time
unsigned long currentTime = millis();
// Previous time
unsigned long previousTime = 0;
// Define timeout time in milliseconds (example: 2000ms = 2s)
const long timeoutTime = 2000;
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(BUILTIN_LED, OUTPUT); // D5
pinMode(15, OUTPUT); // D8
Serial.begin(115200);
// Initialize the output variables as outputs
pinMode(D1, OUTPUT);
// Set outputs to LOW
digitalWrite(D1, LOW);
// 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
// this is the part i want to turn of and on
// to test i only used the built in led (test with 2 external leds work)
// wait for a second
digitalWrite(BUILTIN_LED, HIGH); // D1 Mini: turns the LED *on*
delay(50); // wait
digitalWrite(BUILTIN_LED, LOW); // D1 Mini: turns the LED *off*
delay(50);
digitalWrite(BUILTIN_LED, HIGH); // D1 Mini: turns the LED *on*
delay(50); // wait
digitalWrite(BUILTIN_LED, LOW); // D1 Mini: turns the LED *off*
delay(50);
digitalWrite(BUILTIN_LED, HIGH); // D1 Mini: turns the LED *on*
delay(50); // wait
digitalWrite(BUILTIN_LED, LOW); // D1 Mini: turns the LED *off*
delay(200);
// ----------------------------------------------------------------------------------------------------------------
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
currentTime = millis();
previousTime = currentTime;
while (client.connected() && currentTime - previousTime <= timeoutTime) { // loop while the client's connected
currentTime = millis();
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");// the loop function runs over and over again forever
}
} else if (header.indexOf("GET /5/off") >= 0) {
Serial.println("GPIO 5 off");
output5State = "off";
digitalWrite(output5, LOW);
} else if (header.indexOf("GET /4/on") >= 0) {
Serial.println("GPIO 4 on");
output4State = "on";
digitalWrite(output4, HIGH);
} else if (header.indexOf("GET /4/off") >= 0) {
Serial.println("GPIO 4 off");
output4State = "off";
digitalWrite(output4, LOW);
// 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(".button2 {background-color: #77878A;}</style></head>");
// Web Page Heading
client.println("<body><h1>Brandweerwagen Web Server</h1>");
// Display current state, and ON/OFF buttons for D1

}
client.println("</body></html>");
// 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
}
}
}
// Clear the header variable
header = "";
// Close the connection
client.stop();
Serial.println("Client disconnected.");
Serial.println("");
