O objetivo dele é de apenas aplicar um pulso de 500ms em 2 relés, a página é bem simples e contém apenas 2 botões, um para cada relé, ao clicar no respectivo botão o relé deverá ser acionado por aproximadamente 500ms, sim esse tempo pode ser aproximado.
O problema é que está dando muuuuita diferença no tempo, hora fica os 500ms hora fica uns 5 segundos e por ai vai.
- Código: Selecionar todos
void loop() {
//Caso alguma saída esteja em ON desativa após um pequenotempo
tempoAtual = millis();
if(tempoAtual - tempoInicial>500)
{
digitalWrite(Saida_OFF, HIGH);
digitalWrite(Saida_ON, HIGH);
}
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/off") >= 0) {
Serial.println("GPIO 5 em Low");
//output5State = "off";
digitalWrite(Saida_OFF, LOW);

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("");
}
}
Objetivo desse código é colocar o ESP dentro de uma partida direta e cada relé fica em paralelo com as botoeiras liga e desliga.
