I am glad to announce that Bluetooth HID devices are now supported by the USB Host library. The library already supports PS3 and Wiimote controllers, but now it also supports more general devices, like Bluetooth keyboard and mice.
First time you run the code, you will have to pair with your device, this is done by creating the instance like so:
BTHID bthid(&Btd, PAIR, "0000");
You can of course set the pin to anything you like.
Now you should enable discovery of your device and it should automatically detect any mouse or keyboard present and then connect to them. On Bluetooth mice there is no need to enter any pin, but on a keyboard you should enter the pin on the keyboard and then afterwards press enter.
So in this example you should press 0 four times on the keyboard and then press enter afterwards.
After you have paired with the device, you can simply create the instance like so:
BTHID bthid(&Btd);
When you press any button on your device it will automatically connect to the last paired device i.e. your Arduino. Read more…
I have finally finished my last exams, so now I have more time to focus on some of my own projects. It has been a while since our Kickstarter campaign was successfully funded, but we are still working on making the experience better for the final users.
After the campaign ended we sent out a survey to all our backers with several questions about there address, profession and so on, but we also asked them if they had any suggestions for improvements or extra features they would like to see added to the Balanduino. A lot of people asked if we could enable wireless streaming for it.
I was personally very excited about that since I have been playing with the thought for quite a while, so when the official camera module for the Raspberry Pi became available I bought it straight away.
We are very pleased to announce that our Kickstarter for the Balanduino balancing robot has successfully been funded by $13,494 which we are very happy about.
We have just received stickers from our printing company and have decided to give a little bonus in form of a signed Balanduino post card. We will be shipping this post card and stickers to all of our backers who have pledged $10 or more, within next week.
Hello to all of our followers. This is just a short reminder that the Kickstarter of our Balancing robot, the Balanduino, is nearly finished.
We have already reached our goal of $10.000, but of course it would be great to get even more backers and pledges.
In the meanwhile we have recorded a new video of the robot with a GoPro mounted on the top.
I’m happy to announce that documentation is now available for all the libraries I have written for the USB Host Shield library.
The documentation is available at the following link: http://felis.github.com/USB_Host_Shield_2.0.
The documentation is generated using Doxygen which is a free documentation-generator based upon the header files in the source code.
For instance the following comment will end up looking like this in the documentation:
I hope this will be useful for people who is new to the USB host library or even people who just want a quick overview.

In December last year we developed a small Bluetooth controlled RGB light strip for the christmas tree, to be controlled with your Android smartphone
The demonstration of the project and the smartphone control can be seen in the video below.
The main aspect of the project is to use an Arduino to parse incoming Serial commands to enable and set different effects for the attached RGB strip.
The code for the project, including the Arduino code and the Android application project, can be found on GitHub: AndroidControllableLights
Another interesting aspect of the project was to enable wireless update of the Arduino sketch, using the Bluetooth serial connection. Scroll down in this post if you are only interested in figuring out how this can be done. Read more…
This is a short announcement regarding the USB Host Shield from Circuits@Home, which we are now carrying in in our store.
By buying the official shield you will support the continous development of the library and get support from us!
The shield can be found and bought here: USB Host Shield 2.0 for Arduino.
The shield can be used with almost any kind of Arduino including the most popular Arduino Uno, Arduino Mega, Arduino Leonardo etc. If you are in doubt if your Arduino is supported please don’t hesitate to write a comment below.
You asked for it and here it is.
I finally got the time to implement support for Wireless Xbox 360 controllers to the USB Host Library. This is done via a Xbox 360 Wireless receiver that is normally intended for Windows computers.
The receiver supports up to four controllers internally, so it was fairly easy to implement it.
Actually I havn’t tested the library with more than one controller, but if somebody out there could confirm if it’s working or not, with more than one controller, I would really appreciate it!
Thanks to Tim, multiple controllers is now confirmed to work! Read more…
We at TKJ Electronics have just received a big bunch of inexpensive 2×16 Alphanumeric character display with a built in HD44780 controller, making it easy compatible with the Arduino or any other microcontroller.
We all know that it has been quite a while since we have written any posts on the blog and we apologize to all our readers.
Before telling more about the project and the blog post finally to come I would like to explain the reason for the big delay.
As TKJ Electronics has been evolving quite a bit over the past year we have been provided with a still increasing amount of consultancy work.
This includes everything from PCB Layout, Arduino software development, Robot platform development, ARM processor units and FPGA solutions. Read more…
