Component list for mydooropener project

Postby aurelutz2007 » Mon Feb 24, 2014 1:23 pm

Hi,

I read your pdf with instructions, but is still unclear for me what components I need for the project.
This is what I have until now:

-Arduino uno rev.3
-Ethernet Shield POE Ready Rev3
-DFRobot Relay shield for arduino
-Wall adapter 9V/650mA

In your list there is also a USB2SERIAL kit - do I still need that?
For the moment I can connect to my arduino uno with a usb printer cable.

I will appreciate if you could help me,
Aurel

Hi,

You'll need an Arduino Ethernet combo (no need for the PoE version). This
part includes the USB2SERIAL kit which is required in order to upload software from
your Mac/PC to the Arduino.

You will also need a DFRobot Relay Shield. This is the module that will do the I/O to
open/close and monitor the different devices attached.

You will also need a power supply to have all of this gear powered.

As of 02/24/2014, all parts listed in our latest PDF documentation are still applicable and
valid. Even RobotShop's prices haven't changed since the document was initially authored ... :-)

You're all set to go ... And good luck with the project!

Thanks for you reply,

I bought the arduino uno last year, and since I have that part I would not want to buy the arduino ethernet combo. From your pdf instruction, it seems that I can use the arduino uno+the ethernet shield.

My question it was/is - will I need the USB2SERIAL kit in order to upload the software? Or I can use the USB cable I'm using now: https://www.sparkfun.com/products/512

Hi Aurel,

MyDoorOpener will work with most types of Arduino hardware. There are no hard constraints
except on the TCP/IP stack because we rely on the WebDuino library. So YES, you could use your existing
Arduino Uno + Ethernet Shield and that will work. Your challenge will be to have a Relay board stacked
on top of an already stacked Uno + Ethernet ... :shock:

So NO, you will not need the USB2SERIAL kit if you already are able to upload code to your Arduino Uno
using your existing USB cable.

For the Relay board, on that front too, there are no hard constraints. All I/O pins are configured using constants
in our documented .INO file, so you can change whatever's in there to suit any of the Relay boards available
on the market today. Some people have used the SeedStudio relay board, but we've always worked with
the DFRobot relay boards. Both (and any other) will work.

Best regards,

Thanks for your clarifications. Looking forward to get all the parts together and functional.
