i want DMD connector alone from wher can i get it and i am from india

They are not sold separately, one is included with each new DMD.

Does anyone know of a UK (or maybe EU) supplier for EtherDue?

Coolcomponents don't seem to stock it, and appears to be out of stock.

They should be able to order it for you, or - or order it directly from

Thanks John from Freetronics. Got the freetronics drivers downloaded after I read the paper that came with it. Feeling like a bit of a goose. All is good. great product
Good news, thanks for letting us know.

My arduino is an Eleven R3 with a ATMEGA328P - PU
it is by a company called freetronics and is described as UNO compatible.

I first installed the Arduino IDE 1.0.5 version and extracted it all and then the 1.5.7 BETA was suggested and I tried that too after uninstalling the first.

My problem lies in the fact that I go into control panel>device manager to find the arduino, but there is no sign of it in PORTS and is labelled as unknown device in other devices. I try to upload drivers, but windows always tells me i am unable to install unknown device. I have also downloaded the FTDI stuff, but that hasn't helped.

After a few days trawling the forum I am unable to find anything that solved my problem and I fell I have exhausted all my options. (i assume others have had this problem, however I may have been googling the wrong terms)

Thankyou in advance for your help.

Not exactly a motor shield, however you can control motors using PWM.
The documentation for the shield is terrible, however based on what is provided we'll assume that the six outputs are controlled by Mega PWM pins. So you would use analogWrite() for pins 3~8.  Again, the pin numbers could be different so experiment and see what happens.
For more on analogWrite see:

Please use our USB drivers -

Next time you shop for an Arduino shield, ensure the supplier has made the effort to document the shield for end users before purchasing.

Hi this is John from Freetronics.
Please give us a link to the product page for the motor shield (that has the technical details such as schematic) you are attempting to use with your EtherMega and we can help you with it.

Hey guys,

I was testing out my Arduino hardware using this link:

I can get the motor to move when using a Freetronics Eleven controller board (based on Arduino Uno controller) and the two channel Arduino motor shield. I copied the Void setup code into Arduino 1.0.5-r2 and the motor moved as expected.

However, when I try the same code with a Freetronics EtherMega controller board (based on Arduino Mega 2560 controller) and an Arduino 6 channel motor shield (, I get no movement on the motor at all. The RX and TX lights on the EtherMega controller hardly flash so I assume the Void setup code is the problem.

Is there a Void Setup code that I can try that is appropriate for the EtherMega setup? I have Googled it thoroughly and found nothing.

Also, when I plugged the DC motor into the shield, I made sure to put it into Channel A to match the Void Setup code.

Any ideas?

First of all, try some code for Arduino Uno from your motor shield supplier.
Secondly, how are you powering the lot? And can your provide a link to the technical details of your motor shield?

I want to be able to do the same thing but using this  
I'm just wondering if it's possible and how it would work considering i dont think you can password a bletooth connection can you?

The short answer is yes, you could do this this with Arduino, and yes, it is actually routine to make a bluetooth pairing conditional on a password. This all presupposes this is a worthwhile idea for a project, which it probably isn't.  For starters, you probably have better things to do with your phone and you might have better things to do with the Arduino as well. I think you can do this sort of thing without an Arduino.

If you are serious about being really cool, you might have a talk to Jonathon Oxner at Freetronics.  I understand he has a microchip embedded in his wrist for this sort of thing, and it controls the lighting and security as well.  I imagine he can do this while talking on the phone. I bet Spiderman never thought of that.

We've stayed true to the Due design so the EtherDue has the 1k5 pull-ups, however considering options for the next revision.

Can someone please help? I've tried ABSOLUTELY EVERYTHING!

There is a possibility that you have a problem board. Please email

Might be a little late smiley but we've added an external EEPROM to our new EtherTen/EtherMega boards specifically for storing the MAC address:
13  Using Arduino / Displays / Re: OLED 128x128 plz help on: February 16, 2014, 06:53:29 pm
I have one of the OLED displays and I'm trying to get it to display something    anything really .....
I am trying the examples from the library it compiles and uploads fine but just nothing shows on the screen its puzzling me as to why
I've tried it on an arduino mega 2560 and also an eleven  with no luck
I'm using 1.0.5 of the arduino software and I'm pretty sure i put the library in right but still just cant get anything to come up im connecting it up as the freetronics site says just for the OLED not worrying about the sd slot as of yet
my aim is to start off just making a clock out of it and add more bits in later currently is just a display to show of in the shop at work

any help or some "bare minimum" code would be much appreciated as I'm starting to think maybe i got a dud screen

If you have the Freetronics OLED there's a guide which includes wiring for the display and card socket here:

After wiring it to your Eleven as per the guide, and the display still doesn't work please email to organise a replacement.
