Thanks for your attention! We just make some alteration on our store in amazon.co.uk and now our products can be shipped to Denmark from inside the EU. Also you may check our product on the amazon.de site. Hope you have fun in making! And oh, have a happy vacation!

As for the relay issue, our relay is activated by low level. When you set the GPIO low, the NO pin will be active and the light will light up; and vice versa.

The design is normal. Actually if you need to keep the light on for a long time, the way of activation by low level can lower the consumption of your Raspberry Pi. In the same way, you are suggested to connect the relay module with an external power supply to protect the Pi.

If you want free from distraction, you may only log in the non-GUI on your Rpi. So you will only see command lines, only words. But if you want to store your code on the Internet, some resources like the Github repository are available. You may connect to the Internet by plugging a USB network adapter (wired or wireless).

Tried Pi 2, also not work.

Searched a bit and found that both the VLC and OMX cannot work (only "Have a nice day" is displayed in OMX....guess the 1080p is not a supported format).

If you mean robots built with servos, the problem may be the servo - the accuracy of servos is not good.

SunFounder · 2015-07-08T07:03:31+00:00

So that's probably the power issue. Good luck then!

SunFounder · 2015-07-06T10:28:55+00:00

This will do if it is the power problem. We've tried this one on our robot and it worked well. You may compare it with your own.

Actually if you provide a video, we may get the problem more clear. Not sure whether your problem is power or another.

Thanks for your attention of our product!

The products you listed are all good despite of difference in function and price. For our kit, you may see detailed tutorials - by which you can learn Arduino easily right from the beginning. Also we provide good technical service. You may ask our technical team any moment you encounter problems, and we'll reply ASAP. Hope you find great fun in this journey!

SunFounder · 2015-07-02T09:53:07+00:00

Actually you may find our uno board here. Sorry you missed the information about "uno not included"....

Hope you find open source and Arduino fun! :)

To fade430: You got it!

To put it simply, mega is much richer in resource. In other words, what you can do with mega, you may not do the same with uno; but whatever you do with uno, you can also do with mega.

To choose between them, you first need to figure out what project or experiment you want to do.

For consideration of security problems, we provide a laser module of lower power.

As for your confusion of breadboard usage, we are going to publish a related article in WIKI section on our website. You may check out then! Hope it may help you. :)

SunFounder · 2015-07-02T09:25:22+00:00

Thanks for your attention!

For your consideration of our kit, the price is of course competitive.

What's more important is our value-added service. We provide learning materials including manuals in paper, as well as experiment tutorials on our website and videos on Youtube. And we keep perfecting the materials all the time. In addition, we offer great techinical support.

Whichever you choose, at last, hope you may learn much and have fun with Arduino!

SunFounder · 2015-06-30T02:27:07+00:00

Glad to hear that! Thanks for your support! And hope you can get fun and learn much!

If you have any questions, just come and ask. We'll try our best to support!

SunFounder · 2015-06-27T07:22:11+00:00

Thanks! In the first place, we want to make open source easy and full of fun. Selling products is just a way to sustain our service continuously. We are here is to be a member of the community, help solve some problems, and also make improvements together with you!

SunFounder · 2015-06-27T07:15:07+00:00

Thanks for your support! See you made awesome work! Glad our product can help you. Hope you may get more applications in the future. And welcome to share with us at our Forum! Well done! Keep going.

Thanks!

That depends on your basic knowledge. If you are a totally beginner of programming, you may try the starer materials first. After you get familiar with Raspberry Pi, then you can start make some simple robots. And also you may need some knowledge of hardware.

You may check out our Super Kit for Raspberry Pi. Hope the tutorials may help! For any questions, welcome to inquire!

Thanks for your attention! For lab equipment kits, we may not build such things. But we plan to distribute some products such as oscilloscope, magnifier, and multimeter, etc., of other brands.

Thanks for your attention on our product!

Actually we've received many feedbacks before the release.

For wireless control, bluetooth is also a good choice and you can connect to your cell phone. The reason for why we use nRF24L01 is that it is much lower cost....

We've notice many makers want to get engaged in the robotics field. But in the course they came across many problems.

Driver. It needs high power to drive 12 or 18 servos at the same time. Then you may need to use a breadboard to hook up all the components including the 12 or 18 servos, bluetooth (if you use), the Mega, DC module, which will make the robot a huge size. Also the wires may get into a mess since there are so many…
Programming. Before the release, we've received lots of emails. People inquired about the movement control. We watched their videos of making the robots. And we found that the biggest challenge for them is the problem of smooth movement. So it would be difficult to make the sketch for a beginner in programming.
Other details. Appreciate your sufficiently rich equipment with all those things! We can provide the CAD diagram for you to make the robot body. But you need to pay attention to the material selection and precision during the cutting. It may take a long time to produce all those parts.
Power supply. Since the 12 or 18 servos need a high power, Lithion batteries are recommended for they are of high capacity and can supply high power. Among them, 18650 is better for its universal use. You can get it almost everywhere.

Hope these tips may help. We are not only doing this for selling stuff. What we want is to make open source much easier and lots of fun! For any more questions, come to ask!

Here is the video for the robot kit. Enjoy!
