If your pictures were a sensible size I'd take a look but I have a limited bandwidth.

I can't see them either....

Depending on where you would put your experience level, there is a 'Multifunctional Expansion Board' available on eBay from several sellers. Simple but lots of things to do without the wires.

Read the review. And given that an authentic Uno is 20 euros direct from Arduino (plus tax), but this is less and you get the display too should set the alarm bells ringing.

What you are trying to achieve is fairly straight forward - I hesitate to say easy!

Build a stand alone Arduino on perfboard or similar. You can program the '328 in the Arduino you have, pop it out and plug it into the stand alone.

Use shift registers to output to multiple leds. 74HC595, etc.

A couple of points to bear in mind:
1) the power consumption of the leds. ~20mA each.
2) How many shift registers can you daisy chain together?

Many shields have a software controlled power on and off feature (you didn't provide a link so I don't know if yours does). Even when 'hung' it may respond to this so every so often send an AT command and wait for a response. If no response within a certain time then power cycle the shield.

My guess would be that the page no longer exists but at least they have the courtesy to tell you it has moved elsewhere!

All I can suggest is a little detective work with a regular browser to see if you can find where it has moved to then amend the URL you are posting data to.

The second part of the response code (+HTTPACTION:0,301,344) is 301, and to make it even clearer:

They can draw up to two amps in short bursts. This depends on the network you are connected to and the signal quality. Assume two amps and you won't go wrong!

You guys seem new to me. I'll give you a try sometimes.

I'm happy with their service.

Try a program called SerialRelay to interact with the shield to test it.

Can you provide a link to the shield?
132  Using Arduino / Programming Questions / Re: Set time with one button on DS1307 on: July 15, 2014, 09:30:46 am
It might help if you post all of your code, and if it's too big then add it as an attachment. It's unlikely but the problem could be in the part you have omitted.
133  Development / Suggestions for the Arduino Project / Re: Does Arduino have a future? on: July 14, 2014, 02:47:36 am
I think if it is to have a future then the infamous Uno 'avrdude: stk500_recv(): ' errors need to be addressed. How many new users encounter this issue and don't get a resolution I wonder? And that is probably the last time they spend money on this platform, maybe this hobby.

You might get more assistance if you make your images a sensible size. I'm not downloading a 2.5Mb image.

Did you look at the link in my signature? No libraries used, just AT commands...

Still being edited at the moment.
