# An explanation for the code in this dir
|
||
|
|
|
||
|
|
```
|
||
|
|
AsyncWebServer server(80);
|
||
|
|
```
|
||
|
|
Start the Web Server on port 80
|
||
|
|
|
||
|
|
```
|
||
|
|
WiFi.begin(ssid, password);
|
||
|
|
if (WiFi.waitForConnectResult() != WL_CONNECTED) {
|
||
|
|
Serial.printf("WiFi Failed!\n");
|
||
|
|
return;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
Start the WIFI with `WiFi.begin(ssid, password);` and wait for connection
|
||
|
|
|
||
|
|
```
|
||
|
|
server.on("/", HTTP_GET, [](AsyncWebServerRequest *request){
|
||
|
|
request->send(200, "text/html", "<a href=\"/on\">Turn the LED ON</a><a href=\"/off\">Turn the LED OFF</a>");
|
||
|
|
});
|
||
|
|
```
|
||
|
|
`server.on` Defines an Endpoint for a request (e.g /index.html)
|
||
|
|
|
||
|
|
`request->send(200, "text/html", "<button onclick=\"fetch('http://192.168.178.198/on')\">Turn LED ON</button> <button onclick=\"fetch('http://192.168.178.198/off')\">Turn LED OFF</button>");` on Request answer with 200 in the format text/html with this string
|
||
|
|
|
||
|
|
```
|
||
|
|
server.on("/on", HTTP_GET, [](AsyncWebServerRequest *request){
|
||
|
|
request->send(200, "text/plain", "Was there ever anything here?");
|
||
|
|
digitalWrite(LED_BUILTIN, HIGH);
|
||
|
|
});
|
||
|
|
```
|
||
|
|
This is for when the user clicks on the ON button and fetches the /on url it turns the LED on!
