DO this. Use Serial Monitor in each function call. & print it on serial monitor. Check where serial monitor get stop. If serial monitor stop getting printed that means you have problem after that function call.

Can you post your code and actual schematic.

3  Using Arduino / Displays / Re: 16x2 lcd print only 1 character on: August 19, 2014, 12:33:37 am
First my question is why you are using 2 arduino mega ?? It has more efficient digital ios to achieve using 1 mega board itself.

2) Send me your connection Diagram,

4  Using Arduino / Programming Questions / Re: Software Serial + power source problem on: August 18, 2014, 03:37:26 am
I found out that if I press the reset button after power on everything starts to work. Is there a way to automatically reset arduino on startup???
Yes arduino get reset once it get restarted.

1)DO not power on arduino using both  USB and Vin connected. Either use external USB to serial monitor to view your output data.

2)Can you send image of your Setup

3)Let me know what will happen when you run only on  power supply?? On what basis you are saying that your code is not working  when powered externally.

4) What is VIn voltage you are trying to GIVE.
check this part

5  Using Arduino / Sensors / Re: sh1x error. can not progress my project. need help. on: August 18, 2014, 03:28:15 am
Can you let me  know  which version of Arduino IDE you are using on which OS.

Can you determine PIN out of component used . with detail datasheet
6  Using Arduino / Programming Questions / Re: Music Shield v2 error on: August 14, 2014, 12:08:35 am
Also try to add your library . SO i can check what problem. Unzip below lib and copy to arduino library file. Try to run program.
7  Using Arduino / Programming Questions / Re: Music Shield v2 error on: August 13, 2014, 11:04:58 pm
Check below part of code
void loop()
  myplayer.setPlayMode(MODE_REPEAT_ONE);//set mode to repeat to play a song
  myplayer.playSong("test.wav");//play a song named with test.wav
  while(1);//If the mode is normal, it will stop when it finished playing all the songs in the playlist

Share me  library itself you are working on. Initially i have shared u library have you tried out the library
8  Using Arduino / General Electronics / Re: High current Measuring sensor on: August 13, 2014, 04:02:22 am
On exploring lot
Lot i found that using these kind of amplification network. We can drop the voltage from 1000v in Mv range. can Some suggest me how to use network IC.
9  Using Arduino / Programming Questions / Re: Music Shield v2 error on: August 12, 2014, 11:25:58 pm
Can you post your actual code. That you are trying to upload.
Also share datasheet oF music shield.
10  Using Arduino / General Electronics / Re: Beginner books on: August 12, 2014, 06:05:17 am

just have look over these book. Above book might help you
11  Using Arduino / Installation & Troubleshooting / Re: avrdude: verification error, first mismatch at byte 0x0042 on: August 12, 2014, 06:02:16 am
Have you trying to power on arduino uno using Power supply and USB serial cable. IF yes. Then below error occur.
12  Using Arduino / Programming Questions / Re: Pl help 4X4 Audio Mux dual output problem on: August 12, 2014, 05:58:29 am
Can you shown US ur code.Let  me know your connection diagram.
13  Using Arduino / Programming Questions / Re: Music Shield v2 error on: August 12, 2014, 05:56:35 am
Please let me know your set up
Which version of IDE you are using>>
which controller your using???
provide me connection diagram.
14  Using Arduino / General Electronics / High current Measuring sensor on: August 10, 2014, 11:43:09 pm
Dear all,

I am trying to build string monitor for solar application. There are two ways of doing it. The purpose  to measure current from various string of panel.

1)hall sensor
2)Dc shunt basis.

I have succeed with hall sensor based,. Now i am trying to build DC shunt basis. Is there any one can share how to build it.
any other way you can suggest me of doing it

each current string of 1000V , 20A . There are totally 25 string,

There are totally 25 strings , 1 temperature, 1 humidity.
15  Using Arduino / Sensors / Re: Delphi Universal Oxygen Sensor (Lambda - AFR VALUE) on: August 07, 2014, 11:42:53 pm
Can you share us relevant data sheet of the product.
Mention the output voltage level.
