Hello,
I am new to Arduino and I am having a hard time figuring out how to create a hour meter. I am using an uno with an Ethernet/SD shield. I have that hooked up to sump pump and a transducer. I am able to see the liquid level and control the pump via web page. However, I would like to create a hour meter that records the pump run-time hours, and prints it on to the web page. Here is my code,
#include <SPI.h>
#include <Ethernet.h>
// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = {
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192,168,1,177);
// Initialize the Ethernet server library
// with the IP address and port you want to use
// (port 80 is default for HTTP):
EthernetServer server(80);
*/ LEDpin is used to control relay
int LEDpin = 1;
String readString = String(30);
String state = String(3);
void setup()
{
// start the Ethernet connection and the server:
Ethernet.begin(mac, ip);
server.begin();
//Sets the LEDpin as an output
//LEDpin is actually for relay control
pinMode(LEDpin,OUTPUT);
digitalWrite(LEDpin,LOW);
state = "OFF";
}
void loop()
{
// listen for incoming clients
EthernetClient client = server.available();
if (client) {
// an http request ends with a blank line
boolean currentLineIsBlank = true;
while (client.connected()) {
if (client.available()) {
char c = client.read();
// if you've gotten to the end of the line (received a newline
// character) and the line is blank, the http request has ended,
// so you can send a reply
if (readString.length() < 30) {
readString.concat(c);
}
if (c == '\n' && currentLineIsBlank) {
// send a standard http response header
int LED = readString.indexOf("LED=");
if (readString.substring(LED,LED+5) == "LED=T") {
digitalWrite(LEDpin,HIGH);
state = "ON";
}
else if (readString.substring(LED,LED+5) == "LED=F") {
digitalWrite(LEDpin,LOW);
state = "OFF";
}
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println("Connection: close"); // the connection will be closed after completion of the response
client.println("Refresh: 3"); // refresh the page automatically every 3 sec
client.println();
client.println("<!DOCTYPE HTML>");
client.println("<html><body bgcolor='Gray'>");
// Pump Name
client.println("<center><H1>KO6</H1></center>");
// output the value of the analog input pin
for (int analogChannel = 0; analogChannel < 1; analogChannel++) {
int sensorReading = analogRead(analogChannel);
sensorReading = map(sensorReading, 0, 1024, 0, 300);
client.print("<center> Liquid Level ");
client.print(" is ");
client.print ("<b><font color='blue'>");
client.print(sensorReading);
client.print ("</b></font color>");
client.println("<br />");
client.print(" Hours: ");
//client.print(runtime)
client.println("<br />");
}
client.print("Pump is ");
client.print(state);
client.print("<br><br>");
if (state == "ON") {
client.println("<a href=\"./?LED=F\">Turn Off<a>");
}
else {
client.println("<a href=\"./?LED=T\">Turn On<a>");
}
client.print("</center>");
client.println("</html>");
break;
}
if (c == '\n') {
// you're starting a new line
currentLineIsBlank = true;
}
else if (c != '\r') {
// you've gotten a character on the current line
currentLineIsBlank = false;
}
}
}
// give the web browser time to receive the data
delay(1);
readString = "";
// close the connection:
client.stop();
}
Sorry if my code is sloppy, I am still learning, if anyone could help me it would be greatly appreciated.
Thanks.
