I can't comment on HTML files, but I would have thought that the shield was just a communications device and and the size of the file would be immaterial.

The deafening silence in response to your plea

Anybody else experiencing the same problem?

Is likely to mean "no". This means you need to ascertain why you have a problem that nobody else has, particularly as it is very likely that more people use generic than official shields.

It could be that the shield is suss but, if so, it is probably just that one.
It could be that you are the first person in the universe to tax it with a large HTML file, but it isn't likely, and you don't say what large is anyway.
But the absence of any response suggests that user error is the most likely cause of your problem. This is not to deny that you have fixed a perceived problem, but you might not have fixed the real one.

You need to be more forthcoming about what the problem is. Note that, in the clock project I alluded to, there are two programmes - one to set the time, the other to read the time ( the clock)!

If you are OK with generating the number in Excel and subsequently feeding Arduino, then copying a  CSV to SD and sticking it in the slot is the easy way to go, so forget about Processing.

I'm afraid I don't know much about arrays, particularly the two dimensional ones you are going to need, but some info is here

If you are apprehensive about applying power direct to 5v, don't do it.

If you apply power to the barrel jack, you won't fry anything. That port is good for 12v or more. If you are just fiddling around with blink etc., it will be OK, indeed probably just as good or better than the USB port. In short, fine for little stuff while you save up $5 for a 9v wall wart!
110  Using Arduino / Project Guidance / Re: Is it safe to use iPhone adapter as a power source? on: July 28, 2014, 08:07:25 pm
Probably safe, but not necessarily a good idea. You need to check the voltage first, as it probably isn't 5v, and then check the maximum voltage that may be applied directly to the Arduino.

If you apply the charger directly to barrel jack, it might work, but it needs 7v for reliable operation. You will find out all about this when you add an LCD shield or some LEDs, and will probably conclude that a 9v wall wart was always a good idea. If the charger is no more than about 5.15v it should be OK if applied direct to the 5v pin.   I have a shield that demands a separate 5v power supply. It is fine with an old tablet charger that is 5.15v

It would help if you read the instructions at the head of the forum and posted your code in the proper manner.

If sensors.ino uses hardware serial, it should work properly on the serial monitor as long as the bluetooth is disconnected, so that is the first test. The connection problem is either entirely down to windows, or you have some bad or improper wiring.  You can tedt for the former if you can beg, borrow or steal an Android phone.

Yes, I think I understand now!
I assume your intent is to generate sequences in the spreadsheet I have no idea how you would read direct from Excel into Arduino. The trouble is that Excel and terminal programmes are used for data aquisition, rather than distribution, but I would not be surprised if somebody has done the latter.

I imagine it would be a lot easier to generate the code first and then transfer it to Arduino. The simplest way to that is to use an SD card. You might be able to use a PC programme, like Processing, that reads the file and exports it to Arduino via serial.

I use the weatherproof package from eBay,  complete with plug. They are available with cable length up to 5m. These plug into a home-brewed sensor shield.

I know this is overkill for an alarm clock

You are right about that, so you might also consider staying on this forum, using an Arduino for the alarm clock for a little while, and using the Galileo for something more creative.

No comment on GSM or Yun, but I think Xively and Grovestreams do most of what you need and both are free. Data can be fed continuously, but you may have to generate your own statistics.
116  Using Arduino / Project Guidance / Re: RTC on: July 27, 2014, 07:43:42 pm

In my code i read the time from the RTC in setup, then i sync it to the arduino's time with the Time library. Every time its midnight, i sync it again for precision.
My question is whether this is the best way to use the RTC. I was thinking about reading it every second with a software interrupt and just use that as my time, instead of also using the Time library


This doesn't sound like a good idea at all, and it certainly depends on the RTC you are using and the accuracy you need, neither of which are mentioned. For starters you imply you are using two clocks, neither if which may be very accurate, but one is dependent on the other.

Most projects get by with one clock, so you might explain why you need this to be so complicated. If your needs are valid, you are probably still going about it the wrong way, and I bet you also have the wrong clock.
117  Using Arduino / Networking, Protocols, and Devices / Re: Real Time Clock Module Issues on: July 27, 2014, 07:11:17 pm
, the time that's printed to the serial monitor is 165/165/165 45:165:165.

I think that is a power problem. It is more commonly seen when displaying to LCD. Maybe the RTC is trying to charge its battery. It may be just a poor connection. If you are using USB power, it might be time to change to a wall wart.
118  Using Arduino / Sensors / Re: Multiple DS18B20 on a 10meter long Cat5, not discoverable.... HELP!!!! on: July 27, 2014, 06:49:19 pm
but it seems they had resistors in the metal casing.

I don't think there would be any pull-up resistor in the casing unless the supplier explicitly advised that.
119  Using Arduino / Sensors / Re: Temp Sensor and RTC issue Help Please on: July 27, 2014, 06:43:47 pm

1. I dont know why but the RTC dose not show the real time , each time i diconnect it from the power and connect it again it goes on from the last time ...instaed of getting the real time .

Code:
    setTime(compileTime());    //set the system time to the sketch compile time
    RTC.set(now());            //set the RTC from the system time
 


Possibly the above. Try this

It could be user abuse. I have a few and, while not that accurate, they all work fine. The 3231 is more accurate and hardly any more expensive these days, but the latter may mean it is no more reliable. The one I have is notably more cumbersome, which is something you might need to bare in mind.
