I have a code that turns an LED on and off based on a GET reply from an IP:
#include "WiFiS3.h"
///////please enter your sensitive data in the Secret tab/arduino_secrets.h
char ssid[] = "smarthouse"; // your network SSID (name)
char pass[] = ""; // your network password (use for WPA, or use as key for WEP)
int keyIndex = 0; // your network key index number (needed only for WEP)
int led = A0;
int buzz = 11;
int status = WL_IDLE_STATUS;
WiFiServer server(80);
void setup() {
//Initialize serial and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
Serial.println("Access Point Web Server");
pinMode(led, OUTPUT); // set the LED pin mode
// check for the WiFi module:
if (WiFi.status() == WL_NO_MODULE) {
Serial.println("Communication with WiFi module failed!");
// don't continue
while (true)
;
pinMode(11, OUTPUT);
}
String fv = WiFi.firmwareVersion();
if (fv < WIFI_FIRMWARE_LATEST_VERSION) {
Serial.println("Please upgrade the firmware");
}
// by default the local IP address will be 192.168.4.1
// you can override it with the following:
WiFi.config(IPAddress(111, 111, 1, 1)); //192.48.46.2 before
// print the network name (SSID);
Serial.print("Creating access point named: ");
Serial.println(ssid);
// Create open network. Change this line if you want to create an WEP network:
status = WiFi.beginAP(ssid, pass);
if (status != WL_AP_LISTENING) {
Serial.println("Creating access point failed");
// don't continue
while (true)
;
}
// wait 10 seconds for connection:
delay(10000);
// start the web server on port 80
server.begin();
// you're connected now, so print out the status
printWiFiStatus();
tone(buzz, 800);
delay(500);
noTone(buzz);
}
void loop() {
// compare the previous status to the current status
if (status != WiFi.status()) {
// it has changed update the variable
status = WiFi.status();
if (status == WL_AP_CONNECTED) {
// a device has connected to the AP
Serial.println("A device has connected to the AP");
} else {
// a device has disconnected from the AP, and we are back in listening mode
Serial.println("A device has disconnected from the AP");
}
}
WiFiClient client = server.available(); // listen for incoming clients
if (client) { // if you get a client,
Serial.println("new client"); // print a message out the serial port
String currentLine = ""; // make a String to hold incoming data from the client
while (client.connected()) { // loop while the client's connected
delayMicroseconds(10); // This is required for the Arduino Nano RP2040 Connect - otherwise it will loop so fast that SPI will never be served.
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 to the serial monitor
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();
// the content of the HTTP response follows the header:
// main style
client.print("<style> * {font-family:\"Courier New\", monospace; margin: auto; text-align: center; padding: 15px; box-sizing: border-box;} body {background-color: #69F7BE;} p {border: 2px solid black; border-radius: 10px; font-size:20px; padding: 10px; width: 180px; height: 50px;}</style>");
// slider style
/*
client.print("<style>.slidecontainer { width: 100%; } .slider::-moz-range-thumb { width: 25px; height: 25px; background: #04AA6D; cursor: pointer;}</style>");

*/
// actual functions
client.print("<p><a href=\"/H\">Lights ON</a><br /></p>");
client.print("<pd style=\"height: 10px;\"> </pd>");
client.print("<p><a href=\"/L\">Lights OFF</a><br></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
}
// Check to see if the client request was "GET /H" or "GET /L":
if (currentLine.endsWith("GET /H")) {
digitalWrite(led, HIGH); // GET /H turns the LED on
noTone(buzz);
tone(buzz, 100);
delay(100);
noTone(buzz);
tone(buzz, 700);
delay(100);
noTone(buzz);
}
if (currentLine.endsWith("GET /L")) {
digitalWrite(led, LOW); // GET /L turns the LED off
noTone(buzz);
tone(buzz, 700);
delay(100);
noTone(buzz);
tone(buzz, 1100);
delay(100);
noTone(buzz);
}
}
}
// close the connection:
client.stop();
Serial.println("client disconnected");
}
}
void printWiFiStatus() {
// print the SSID of the network you're attached to:
Serial.print("SSID: ");
Serial.println(WiFi.SSID());
// print your WiFi shield's IP address:
IPAddress ip = WiFi.localIP();
Serial.print("IP Address: ");
Serial.println(ip);
// print where to go in a browser:
Serial.print("To see this page in action, open a browser to http://");
Serial.println(ip);
}
how can I add a slider that passes a variable to the code so that I can analogWrite() the led with the value?
