Hello, I builded a small counter that uses an infrared sensor to count objects on a conveyor.
However i want the counter to send the number of the counted object by network into a database.
Here is the code i use for counter to display the number on LCD:
int buttonPin = 2; // the pin that the pushbutton is attached to
// Variables will change:
int buttonPushCounter = -1; // counter for the number of button presses
int buttonState = 0; // current state of the button
int lastButtonState = 0; // previous state of the button
void setup() {
// initialize the button pin as a input:
pinMode(buttonPin, INPUT);
// initialize serial communication:
Serial.begin(115200);
clearScreen();
}
void loop() {
// read the pushbutton input pin:
buttonState = digitalRead(buttonPin);
// compare the buttonState to its previous state
if (buttonState != lastButtonState) {
// if the state has changed, increment the counter
if (buttonState == HIGH) {
// if the current state is HIGH then the button
// wend from off to on:
buttonPushCounter++;
clearScreen();
Serial.print("Numar placute: ");
Serial.println(buttonPushCounter);
}
}
// save the current state as the last state,
//for next time through the loop
lastButtonState = buttonState;
}
void clearScreen(){
Serial.write(byte(0x7C));
Serial.write(byte(0x00));
}
And here is the code that i think i have to combine with the previos one to get the data on the network:
#include <SPI.h>
#include <Ethernet.h>
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; //physical mac address
byte ip[] = { 192, 168, 1, 102 }; // ip in lan
byte gateway[] = { 192, 168, 1, 1 }; // internet access via router
byte subnet[] = { 255, 255, 255, 0 }; //subnet mask
EthernetServer server(84); //server port
int buttonPin = 2; // the pin that the pushbutton is attached to
int buttonPushCounter = -1; // counter for the number of button presses
int buttonState = 0; // current state of the button
int lastButtonState = 0; // previous state of the button
String readString;

//start Ethernet
Ethernet.begin(mac, ip, gateway, gateway, subnet);
