Make your own Raspberry Pi 2 DIY LED LAN device counter

Over at the Bergen hackerspace in Norway the members needed a fast way to determine how many devies were connected to their local area network at the same time, and came up with a neat solution based on a Raspberry Pi and Arduino-compatible circuit. A clear indication of their requirements is displayed using Arduino-controlled 7-segment LED displays.

The Raspberry Pi interrogates the network every ten minutes, determines the number of devices and sends the value to the Arduino side via serial. The value is interpreted by the Arduino and reflected in the LED displays.

This project is not only a useful project but also a good example of maximising the synergy between a Raspberry Pi and Arduino. For details on making your own counted, visit the project's Instructable page. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.

For more complex Raspberry Pi projects that require interaction between an Arduino and a Raspberry Pi for enhanced hardwre control you can save time and space by using our new PiLeven board:

The PiLeven is an Arduino-compatible board based on the Arduino Uno, but with a few changes. Obviously it's a bit of a strange shape! The PiLeven fits right on top of a Raspberry Pi (either model B or B+) using the Raspberry Pi expansion headers.

The PiLeven also has a high-current switchmode power supply, so you can plug in anything from 7V to 18Vdc using the standard 2.1mm jack. The PiLeven can power the Raspberry Pi, so you don't need a regulated 5V USB connection anymore.

Serial communications on the PiLeven is linked through to the Raspberry Pi, so your Pi can upload new sketches straight to the PiLeven or send/receive data and commands. We've included level shifters so the 3.3V Pi can talk safely to the 5V PiLeven. And you can plug standard Arduino shields right into the PiLeven, giving your Raspberry Pi access to the huge range of shields already available. For more information about the PiLeven, including our tutorials - and to order yours today, visit the PiLeven webpage.

Build your own Arduino-based games console

Making your own video games may seem difficult, however nothing could be further than the truth. And your Arduino or compatible board has enough processing power to run a wide variety of classic video games that are quite enjoyable - so why not make your own?

A great example of doing so has been documented by Joao Vilaca who uses an Arduino-compatible, analogue joystick and a colour display to play games such as Tetris and Breakout. As you can see from the video below, the gameplay is acceptable and runs like the original:

For all the information and sketches required to make your own, visit Joao's interesting website.  And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well.

If you're looking for a neat and colourful display to use with your Arduino or Raspberry Pi - consider our 128x128 pixel OLED Module. With a diagonal size of 1.5" and 16,384 colours to select from, so almost anything is possible. Furthermore there's a microSD card socket, and removable tabs on each side which can hold LEDs and buttons:

And using the module is made simple - we have tutorials and drivers for both the Arduino and Raspberry Pi platforms - great for experimenters or those who use both systems. Furthermore, check out the forum where members are already creating modified drivers to rapidly increase the display speed. For more information including our Quickstart guides - and of course to order - visit the OLED Module product page.

Easily control DC and stepper motors with the HBRIDGE Shield

We frequently receive requests for helping people use motors with their Freetronics Eleven or other Arduino-compatible board - and the solution is usually our Dual Channel H-Bridge Motor Driver Shield. It's quick and we also have a neat tutorial with some demonstration code that shows how to use both DC motors or a stepper motor.

Taking this explanation one step further is Mr Hobbyelectronics, whose latest video is an introduction to the Freetronics Dual Channel H-Bridge Motor Driver Shield and shows us how easy it is to control DC or stepper motors in no time at all. Check out the following video to learn more:

For this and other interesting videos related to the Arduino, Raspberry Pi and technology world - subscribe to Mr Hobbyelectonics' YouTube channel. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well.

If you're looking into starting with Arduino and robotics, such as controlling a stepper motor (or DC motors) from your Arduino or compatible, check out our HBRIDGE: DC/stepper motor shield.

Based around the powerful Allegro A4954 H-bridge driver IC you can control two DC motors with complete ease, or one bipolar stepper motor. With connections for external power management, a complete beginners' guide and documentation - motor control couldn't be any easier. For more information and to order, visit the HBRIDGE: page.

Build you own version of the "Berlin Clock" with Arduino

Next in the line of interesting and different clock projects is a functional replica of the "Berlin Clock". The Mengenlehreuhr as it is know in German is the first clock in the world to display the time using set theory. The lamp at the top blinks for seconds, then the next two rows down denote the hours, then the following two rows for minutes.

This is certainly a different way of displaying the time, and once fitted inside an enclosure would make an interesting talking point for any home or office. Constructing your own is easy thanks to the creator Marc Deloor, who also simplified the LED control by using a MAX7219 LED display driver. Although only in prototype form below, you can see how unique it is:

To make your own version, check out the project page. And to learn about the original Berlin clock, visit Wikipedia. And for more, we're on facebooktwitter and Google+, so follow us for news and product updates as well.

The most important part of any clock project is the inclusion of an accurate real-time clock IC. Here at Freetronics we have the Maxim DS3232 real-time clock IC module:

Apart from keeping accurate time for years due to the temperature-controlled oscillator and having a tiny coin-cell for backup, it is very simple to connect to your Arduino project. A driver library allows your program to easily set or read the time and date. Perfect for clock projects, dataloggers or anything that needs to know the date and time. Furthermore it contains a digital thermometer and 236 bytes of non-volatile memory to store user settings and other data. For more information, check out the module page here

Displaying Images on the Freetronics DMD LED Display with Node.js

There are many uses for our large DMD Dot Matrix Displays, and we're always excited to see new ways of interfacing with and controlling these super-bright display units. An excellent example of this has been demonstrated by Patrick Catanzariti who shows how easy it is to control a DMD with an Arduino and Node.js on a host PC.

The combination of Arduino and Node.js is used to decode a .png image file, and send the image data to the display. As you can see from the image below you can convert any image with a size of 32 x 16 pixels, and thanks to Patrick's code you can recreate this yourself.

Furthermore the article includes a neat explanation of how the DMDs are controlled with the Arduino sketch so you will have a mastery of the subject in no time at all - so click here to get started. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well. 

If you would like to have fun with node.js and a large LED dot matrix display - check out the Freetronics Dot Matrix Displays. They're simple to use, yet very bright for indoor and outdoor situations. Available in various colours, the 32 x 16 LED matrix can display text and graphics quite easily - and can be daisy-chained together for extended displays. For more information, see our range of Dot Matrix Displays here

Controlling motorised desks with The Force and Arduino

For those of you lucky enough to have a motorised desk at the workplace that allows control of the height at the push of a button - it's now possible to create your own heigh controller that can give the uninitiated the view of seeing you move a large object with only the wave of your hand.

The hardware to make this possible has been documented by Joakim Christoffersson, who hacked the motorised desk height controller by adding an ultrasonic distance sensor and an Arduino to the mix. The sensor is enclosed in a neat case, and detects the distance between itself and the user, which is then used to control the desk motors. And thus you can then be seen to control the desk with "The Force" - as shown in the following video:

 Certainly something different and a lot of fun. To learn how to make your own version, check out Joakim's project page. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.

If you need to add external hardware or devices to your next Arduino project, you'll need a protoshield to mount the external circuitry. In doing so, consider our range of ProtoShields. From the tiny LeoStick to the Mega we have a wide range to suit your application.
