Adding gesture control to a mechanical maze with Arduino

Interfacing with various types of user inputs is easy with an Arduino, and a popular method is using the Nunchuk controller from a Nintendo Wii. As the controller uses the I2C bus to communicate the controller's data can be interpreted by an Arduino without too much work. This can then result with interesting control projects, such as this mechanical maze.

The X- and Y-axis knobs have been removed and replaced with small servos, which can then be rotated with the Wii controller for a remote-control maze as demonstrated in the video below:

Even if you're not working on a maze, this is a good demonstration of how to add Nunchuk control to an Arduino for your own purposes.

The "Illumaphone" - a light-based Arduino-controlled musical instrument

With some imagination and an Arduino you can make all sorts of musical instruments, and the following example by Bonnie Eisenman is an excellent demonstration of what can be done. Created for a university project, hter "Illumaphone" uses light sensors for different music notes - with each sensor used to control the volume and vibrato for each note.

The sensors are arranged in small cylineders allowing the artist to control the amoutn of light falling over each sensor. Then the Arduino takes the data from the light sensors and converts this into commands for a PC running musical synthesiser software and finally into sounds. A demonstration of the Illumaphone is given in the following video:

To learn more about this project and the construction details, visit the project page. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well.

Looking for a light sensor? Although it can be tempting to use a light-dependent resistor, they're fragile and can give varying results. Instead - consider our LIGHT: light sensor module based around the digital TEMT6000 sensor. It gives consistent and reliable readings, and is incredibly easy to use with our Getting Started guide.

Make an Arduino-based MIDI sound synthesiser

Thanks to the ease of controlling digital inputs and outputs, an Arduino or compatible board works well with digital audio hardware that has a MIDI interface. In this example by Instructables member Christhian180 an Arduino programmed with various sound data can be controlled with a MIDI instrumnet - in this case a keyboard, and used to make all sorts of sound or effects.

For sound output a simple amplifier circuit based on the classic LM386 is constructed which takes the output from one of the Arduino's PWM outputs and boosts it for use with an external speaker. It's a lot of fun, and a quick demonstration is given in the following video:

To learn more - 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.

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.

Musical beat detection using an Arduino

Digital signal processing is usually a task for PCs with customised software or at least 32-bit microcontrollers - however with some clever coding an external circuitry an Arduino or compatible can also perform some functions, and one of these is beat detection.

This process is explained by Damian Peckett who not only explains various methods of DSP methods but also the Goertzel Algorithm used in his project. With the addition of a small preamplifier circuit the Arduino can receive an amplified signal from an electret microphone and determine the lower-frequency sounds.

For more information about the process, including example circuits and sketches - visit Damian's interesting website. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.

Make an Arduino-controlled time lapse camera dolly

Using an Arduino or compatible to control a camera for the purposes of time lapse photography isn't that new, however combined with other hardware all sorts of options can be created. One interesting example is a time lapse camera dolly - whic is a small robotic wheeled device that can not only control camera exposures over time, but also move itself between shots.

This has been documented by Instructables member Inevitablecraftslab who has created a small dolly which is propelled via a continuous rotation servo. This allows for easy control by the Arduino and some interesting effects, such as time lapse photography of a flower opening, and chaning the angle of the exposure after each movement.

To learn more about this, 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.

 If you're looking into starting with Arduino and motor control, such as controlling a DC motor (or stepper motor) 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 your own functional "Sonic Screwdriver"

Electronics enthusiasts who are also "Dr Who" fans will love this new project by Instructables member Honus who has created their own version of the Time Lord's sonic screwdriver based around an Arduino-compatible and some excellent handiwork.

And apart from looking great, the screwdriver is also quite interactive - and apart from various lighting effects it can also log temperature and humidity to a microSD card inside the unit itself.

This is a great project, and well worth investigating from the Instructable page. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well.

Looking for a small Arduino-compatible board to embed in various projects? Then consider the Freetronics LeoStick - It's the Arduino Leonardo-compatible board that's cheaper and smaller than the original:

Controlling LEGO Power Function trains and models with Raspberry Pi

The later LEGO trains and Technic examples are controlled via the "Power Functions" system, which is in effect a simple infra-red remote control for the user and an IR receiver connected to the motor unit in the train or model. Thanks to the relatively simple nature of the IR signal used and the open-nature of LEGO's documentation - it's easy to reverse-engineer it and create your own controllers.

Alan Nishioka has done just that, by deconstructng a PF remote control, and analysing the signal using a digital storage oscilloscope. With this data he's created a Raspberry Pi-controlled IR transmitter that can be the basis for all manner of Pi-controlled LEGO trains or Technic models. Furthermore with the addition of a Bluetooth LE module, the battery charge can be monitored and reported back to the system when low.

This is a great example of how consumer toys can be modified for even great control, so visit Alan's interesting website to get started. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.
