If it's the DS1307 you are using, it is not a particularly accurate clock and buying 2 more from a different source probably won't help. The DS3231 is considerably more accurate.


Absolutely. Plus the temperature affects the external crystal/capacitors for the oscillator.
DS3231 or DS3232 is the go.

Get one of these:
Serial control at one end, speaker output (max 3W) at the other, microSD socket for MP3 files on card.
3  Topics / Home Automation and Networked Objects / Re: Arduino Mega 2560 board that has Bluetooth built in on: July 02, 2014, 06:11:57 pm
Maybe you can help us out a little more.
Do you need the Mega for the extra I/O or memory space? (or both!)
For example if you need the I/O you could use an BLUNO with some I/O expansion:

You could store the incoming data into a string and then parse it.

Your videos are very useful, but to complete the picture perhaps put your code and notes in a blog, github page or similar - including existing videos. Otherwise your viewers will get frustrated and leave you alone.

And I've updated it with some more remote-control examples:
9  Products / Arduino Due / Re: Error while trying to compile the D3232 RTC library on: December 16, 2013, 04:21:15 pm
That library was written by a third party before the Due. Just use normal I2C commands, there's a guide on how to do it: and scroll down to
Controlling The RTC Module Via Direct I2C Commands
10  Topics / Education and Teaching / New tutorial - numeric keypads on: December 15, 2013, 11:38:55 pm
Have consolidated and updated the Arduino and numeric keypad tutorial:
Have fun
11  Topics / Education and Teaching / New tutorial - the AREF pin on: December 12, 2013, 01:53:07 am
Have updated the AREF tutorial. It's pretty self-explanatory:
12  Topics / Education and Teaching / New tutorial - Arduino and Ethernet on: December 05, 2013, 07:29:01 pm
Have updated the Ethernet tutorial. Covers getting started with your Ethernet shield through to displaying sensor data on a webpage you can access remotely:

I understood to be an external service, no?

The library uses this site as a proxy server for OAuth stuff. Your tweet may not be applied during maintenance of this site.

I was thinking along the lines of something like Temboo, cosm etc. - things you have to pay for.

Currently in the process of rewriting a few of my tutorials, and have just finished the first of possibly more twitter chapters. We show you how to send tweets that include plain text and also data from an Ethernet-enabled Arduino board without any paid external services.
15  Products / Arduino Yún / Tutorial – Send email with the Arduino Yún on: November 22, 2013, 08:50:15 pm
Next in my series of Arduino Yún tutorials is a guide on how to send your own data from the Yún as an email via a Google mail account.
