GPS CLOCK 7 SEGMENT LED DISPLAY NOT WORKING

by ucdailoi on Sat Feb 06, 2016 9:19 am

Its my very first attempt at Arduino, so please be kind :)

I have put the project together very carefully using the exact same parts listed.
The Arduino board is lit with the 2 lights.
The GPS flashes and then locks on as it is supposed to...
I have loaded the software (I hope), but
The 7 segment LED shows no sign of life... I then tried a second 7 segment LED which I had but it is also dead..

How do I start to trouble shoot this project?

Thank you

The best place to start is with some photos showing your soldering and connections to the display.

Thank you.... I take some pride on my soldering... so here goes..

With 2 more solder joints to go...

Is there some way I can confirm that the software has been loaded or installed?

Dont forget this is all totally new to me.. My experience is only with computers and if software is installed I can see it.. Is that also the case with the Arduino?

Thank you

The solder looks great and the connections appear to be correct. If you open up the Serial Monitor, do you see the "Clock starting!" message? (You will need to set the Serial Monitor baud-rate to 115200).

AH HA..... Its midnight here now so I will check tomorrow... I suspected the software installation might be the issue.. Ill check that tomorrow and get back to you.

Thank you

Success.... It was the software which I was having trouble installing...

Thank you

Good to hear it's working. Thanks for the follow-up.

Booted it up today and it wouldnt work properly then after a reboot it worked fine...

The next stage is to build it into a suitable container.

Thank you again

That means that the Arduin IDE is not able to communicate with your processor. You can try clicking on the link provided. Or contact the manufacturer of your Arduino compatible processor. (Not sure, but it looks like one of the DFRobot boards.)

Its been working OK ever since...

I havent checked the details of the web site but my question is "What can I do with the clock during Daylight Saving, where the clock goes back an hour for several months before reverting to normal time again"

We have a crazy system here in Australia where only some states apply "Daylight Saving" so travelling between states will require an external adjustment..

Your help is appreciated

Oh, you've hit on a sore point. I'll do my best to keep this a civilized rant :)

Messing with the clock may have been less of a dumb idea back when clocks were just clocks. But in this highly connected world, tracking and timing the sequence of global events is a real challenge when different parts of the world decide to change their time-base at arbitrary times of the year.

We have a crazy system here in Australia

It is similarly crazy here in the states. And the local start & end dates can change at the whim of the local politicians. You can just ignore it like I do. My day starts when the coffee is brewed ;)

To deal with it in software, the best approach is to calculate everything based on UTC (Universal Coordinated Time) which is essentially the same as GMT (Greenwich Mean Time). Then calculate the local time-zone of the moment as an offset from that. East coast of Australia would be UTC + 10:00. East coast of the US is UTC - 5:00. To change the time-zone, just increase or decrease the offset.

Thank you.... so from my understanding of what you said I will need to be able to adjust the time by a software adjustment which means that when I build my clock into a small box it will need a USB port?

Is it possible to access the software running on the Arduino in order to modify the program or do I overlay it with the adjusted time?

You could re-load the code. But it would be more convenient to design your code to use a couple of pushbuttons for adjusting the time-zone.
