I am using an arduino uno, will your info on the HID.cpp file still apply?

The code is for the Leonardo but you cannot use that code anyway because it's for USB and not BT. But you can get an idea about how HID works.

Re: How can One Turn 2.5V from Capacitor into 12V @ 1A DC Motor

Thanks for the quick answer. But I do not need 10A, only 1A.

I thought caps can supply immense quantities of current. Don't they use them in magnetic rail guns, where caps discharge torrents of current in a millisecond?

Sorry Coding, got a little anxious there smiley

Thanks for your reply. Storing fixed point would mean that I'd have to multiply everything by 100, and my highest value would be 10,000. I'd have to get into storing doubles then. I also have to store the tim...

Warum verwendest Du keine Optokoppler? Bei den Tastern mußt Du ja keine großen Ströme schalten.

Record and playback audio, also via ethernet.

Posted: 08 Mar 2013 01:01 AM PST

I have seen many wave/audio/mp3 shields, but I still don't know how to do this.

What is a good audio shield which is also able to record sound ?
The input can be a electret mic or a line-in.

The next step is using it together with the Ethernet Shield.

Pi + Node = Interactive, Internet Connected LED Message Board #piday #raspberrypi @Raspberry_Pi

Posted: 08 Mar 2013 01:00 AM PST

CompletedPiNode

Check out this great Pi + Node LED Message Board project. Luke Berndt told us this about it:

Hi Guys, I used a bunch of your parts to build an LED Message
Board that is powered by a Raspberry Pi using the SPI Bus. The LED Modules I have use the HT1632 chip, so the code could work with some of 16×24 LED displays you have. I also wrapped my C++ code as a Node module, which made it easier to display headlines from the Internet. For a final touch, I turn the Raspberry Pi into an Wifi Access Point, to make it easy for my co-workers to add messages. Anyhow I have spent way to much time fooling around with it and wanted to pass it along so other might get some use from the code and my mistakes.

From Berndt's documentation:

While it is great to have the latest headlines up on your message board, it is even better being able to add in a message about how thankful you are that it is Friday. The final touch for my LED Message Board project was to add in a web page that made it easy to update messages. Of course, giving your friends a way to post Star War jokes on your message board only makes it more fun, so I added a Wifi and used HostAP to make the Raspberry Pi look like an access point. To make it even easier to post, I made the Message Board web page a captive portal. So now all one of my co-workers has to do is try and join the "Message Board" Access Point with their iPhone and they are brought to the webpage that lets them add and delete messages. Finally, since it is all Node based and I wanted to play with Socket.Io, I made the message list update in realtime. Now when new messages are added or the ESPN Headline is updated, everyone viewing the webpage gets to see it change.

The Code for this is up here.

Check out how I wired/coded everything and created a Node module to write to it.

I have the LED Modules mounted in a wooden case that is held in my office door frame using magnets. It is positioned so that it shows through the frosted glass next to my door.

The Arduino is the best microcontroller to do so. Lots of example is code is available, and we are glad to help.

You can use the same (ceramic) capacitor to serve as both the output capacitor for the 78L05 and the decoupling capacitor for the ATtiny, if those components are close together.

In the diagram above, you appear to have put the flyback diode in series w...

Code can / should have unique names for variables. That variable can have diffrent values but you can not declair the same variable name more than once.
