4  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:

I understood http://arduino-tweet.appspot.com/ to be an external service, no?

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.

Currently in the process of rewriting a few of my tutorials, and have just finished the RFID chapter. We use the inexpensive little readers that are available to demonstrate how to read and recognise 125 kHz tags:

13  Using Arduino / Displays / Re: Sainsmart 3.2" TFT with Adrduino Duo - I just don't get it! on: November 16, 2013, 12:48:35 am
I've been searching all over the place, but I can't find any definitive answer as to whether I can get this http://www.sainsmart.com/arduino-compatibles-1/lcd-module/sainsmart-3-2-tft-lcd-display-touch-panel-pcb-adapter-sd-slot-for-arduino-2560.html to work on an Arduino Uno, and if so, how it gets hooked up (needs a shield? uses all 20 pins).

Been looking for a basic, cheap, color LCD (doesn't need to be touch) to use in an Arduino project, and having so much trouble!

Any guidance would be greatly appreciated.  Thanks!

According to the "document" tab on that prouduct website the LCD is for R-Pi or Linux.
14  Using Arduino / Displays / Re: DMD conflict with an RF installed in the same board? on: November 16, 2013, 12:45:43 am
Dear all,

I have two Arduino boards connected by RF transmitter/receiver. The one with the receiver is also conected to a Display Matrix Dot.
At first, there is no pin conflict, but when I try to control both components, they are not working together. Only when I'm removing the code from one of them, the other one works.

I think there is a conflict with the timer libraries, because probably both are using them. Any suggestions to make them work together?

Ignacio

P.d. This is the model of the RF boards: http://www.lipoly.de/index.php?main_pag ... 19afbl3nf3 , And this is the DMD: http://www.freetronics.com/collections/display/products/dot-matrix-display-32x16-red

You will have a pretty heavy conflict with the Timer library used by the DMD and the VirtualWire library for your RF. I'd change wireless hardware to something that uses serial between the radio module and the Arduino (e.g. XBee) - then you won't have any conflict.

After reading all that, I went and made a double ristretto and pondered your project. Biggest trial I can see is getting the pod in and then pushing the lever which locks it in.
