1  Using Arduino / Project Guidance / reading digital values to a remote web server on: April 23, 2013, 12:33:19 am
I'm using Arduino + Ethernet Shield and reading digital values that change relativelly quickly. I'd like to send these values to a remote web server to be stored in other to manipulate them later. Do you know how I could do this ?

how can i reset the millis() ?
i have done for RED
the folloing is the program for it...

unsigned long time, previous, key;
int red = 2;
int row = 0;

void setup(){
void loop()
   while(digitalRead(red) == LOW);
 Serial.print("DATA,TIME,"); Serial.print("ON,"); Serial.print("RED,");Serial.println("  ");

  time = millis();
   while(digitalRead(red) == HIGH);
   previous = millis();
     key =  previous  - time ;
    Serial.print("DATA,TIME,"); Serial.print("OFF,"); Serial.print("RED,");Serial.println(key/1000);



  //prints time since program started

I am Vennish Muthu, M.Tech Mechatronics, V.I.T University, vellor,tamil Nadu.
Good to see more number of INDIANS out here.
4  Using Arduino / Project Guidance / Re: Knee Recording Joint movement (Knee) on: January 08, 2013, 12:56:19 am
hey jus try using a potentiometer with some mechanical changes this will be really effective .
i had already tried this to find the angle of a robotic arm.
The change in resistance can be noted at each angle.
5  Using Arduino / Project Guidance / Data Tracking with Machine Status Light on CNC machine. on: January 08, 2013, 12:36:37 am
My project deals with counting number of parts produced and to record the time and time duration when a CNC machine stops and starts  and i need to do this with my Adruino UNO or Leonardo.

A Machine Status light is a tower of GREEN, YELLOW, & RED lights kept above a machine to observe the status of operation.

The logic is simple i need to count the number of components produced in a CNC tracking the glowing of GREEN light.Say the greeen light glows for 180sec. So that whenever green glows for 180sec  the count should updated.

Also if YELLOW and RED light glows for some duration the time duration it had glowed should also be noted.

GREEN : The CNC program is running , i.e cycle is running
YELLOW : The CNC machine is stopped for loading and unloading the workpiece.
RED : The CNC is stopped and no operation should take place.

Please could someone help me with the LOGIC.(Programming part)
6  Using Arduino / Project Guidance / LED glowing time calculation on: January 05, 2013, 08:07:07 pm
Hai All,
     By using arduino uno I want to display the LED glowing time in serial window say example if I connected one LED in 2 pin and I glow it for 30 seconds means in the serial window I want to show 30 sec like that. Please  guide me.
7  Using Arduino / Project Guidance / Data Acquisition from Vernier to PC. on: November 21, 2012, 04:20:46 am
Hey guys i am doing a small project on Data Acquisition from a vernier Caliper to PC.

i was some what successful in transferring the data from Vernier to Arduino Serial window Screen.
but now i want to transfer my data to a Excel file.

 I have used the PLX-DAQ software but i frankly don’t know how to use this software,should we program some where or if we connect directly will it work.

can someone help me out...
