We are happy to announce a new contributor and hopefully soon consultant at TKJ Electronics, Diego Ayala.
I have been in touch with Diego for quite a while and we have been talking about his experience with the STM32 family and other ARM M0, M1 and M4 cores together with the Keil and CooCox IDE’s. So an experience like his is really usefull for ARM embedded projects.
To display some of his work we decided to go thru one of his recent projects, a color tracking device running on the STM32F103. A project that really displays what the ARM Cortex-M3 device is capable of doing, as long as you optimize well enough.
It has been quite a while ago since my last post here at the Blog which is due to a lot of new things and changes that happened in the past year. So with the following post I would like to tell a bit about myself and why I haven’t been writing post so frequently.
“Who am I?”
Most of you probably don’t know a lot about either me or Kristian, but I thought it would be the right time now to give a better introduction about me and myself. I have mainly been keeping these details about myself private, due to my age and the difficulty in freelance work and consultancy when being a newly started company and now with an age of only 20 years.
“My name is Thomas Kølbæk Jespersen. I’m 20 years old and a keen electronics enthusiast, entrepreneur, R&D ‘engineer’ and now being a student at Aalborg University studying Electronics Engineering.”
A lot of things happened for me and my company TKJ Electronics in the past year, which are but not limited to:
I am very pleased to announce that I have now added support for the PS4 controller via Bluetooth. This will allow you to read all the buttons and joysticks with the same API as all the other libraries I have written for the USB Host library.
To get started you should look at the provided example. It shows how to read the different buttons and joysticks. I still haven’t figured out how to control the light, rumble and read the accelerometer, gyroscope and touchpad, but hopefully I will figure that out soon. Read more…
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:
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.
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.
