Cool project!

Just to let you know, you can do this with analog circuitry as well....

I didn't explain it well...My bad...
I wanted to wire it on my own. I want to make my own SD card reader. I was wondering if I could do this directly to a USB with wires, or if I could use an Arduino to accomplish this. Sorry for not being clear!!

Ok...Thanks. I am using the same one. Wow 100ma? That is surprising!

Hi everyone!

I am new to using the Arduino to interface an SD card, so I need help on this project. Is there a way to use the SD card as a FlashDrive? Is there a code out there to use the SD card as a USB flashdrive? Can I wire it up directly to the USB in such a way to have it work as a flashdrive? Thanks!

Make sure to keep it connected to ground. Secure your connections, too.

Is that the SD card you have?
8  Using Arduino / General Electronics / Re: Solar Power on: November 21, 2012, 03:25:19 pm
Purchase a 9 volt solar panel from Radio Shack and regulate its voltage to 5v to power the Arduino. Use the regulator LM7805, also available from Radio Shack.

I recommend the 2N3904 for the switching application of the transistor....They are extremely cheap, and I bought 50 for .07 cents apiece and Mouser Electronics. Here is the link: ALL PRODUCTS

They are high quality, and cheap.

You could record the word through a recording module available at Radio Shack, and transmit this wirelessly through wifi with an Ethernet shield or a WiFi shield. The cheapest way to do it is through infrared as johnwasser said.
11  Using Arduino / Project Guidance / Re: Can you fit a L298 and an Ethernet shield on an arduino uno??? on: November 21, 2012, 03:07:58 pm
Yes...I think it does, but I might be wrong. Research it, and then if they do not fit together, then you might want to look into the wifi shield for Arduino to see if it fits with the L298. Good luck with your project!

Ok...I did not realize this. Thank you for pointing it out, but I did not complete Lake's suggested project...I took your advice and did a little research, then completed the project...Thanks for your help again! (It works)
13  Using Arduino / Project Guidance / Re: arduino with wiimote? where to start? on: November 21, 2012, 03:02:15 pm
Cool project!

Inside the remote is an accelerometer that communicates with the Wii through bluetooth. To receive the signal, you will have to purchase a bluetooth shield for Arduino available online or at some Radio Shacks. Does it have to be a Wii remote? You could purchase an accelerometer at Radio Shack and make your own controller circuit...Anyway, here is some info on the bluetooth communication:

"It is built around a Broadcom BCM2042 bluetooth System-on-a-chip, and contains multiple peripherals that provide data to it, as well as an expansion port for external add-ons. The Wii Remote uses (and, at times, abuses) the standard Bluetooth HID protocol to communicate with the host, which is directly based upon the USB HID standard. As such, it will appear as a standard input device to any Bluetooth host. However, the Wii Remote does not make use of the standard data types and HID descriptor, and only describes its report format length, leaving the actual contents undefined, which makes it useless with standard HID drivers (but some Wiimote Drivers exist). The Wii Remote actually uses a fairly complex set of operations, transmitted through HID Output reports, and returns a number of different data packets through its Input reports, which contain the data from its peripherals."

Good luck with your project!!  smiley-grin

You need to purchase a wifi or Ethernet shield. Good luck on your cool project!
