Local browser control of an Arduino with “Webduino”

If you’re prototyping with Arduino-controlled hardware and get frustrated or don’t have much time to keep writing test sketches to test the hardware, Webduino might be the answer. Developed by Cooper Maa, it allows simple control of the I/O pins including PWM, input and output modes via a web browser. The Arduino needs to run the firmata sketch, and can update around 50 ms intervals. You’ll also need to run Node, NPM and CoffeeScript on the host PC, however the resulting interface is worth it, for example:

If you’re new to Arduino, the first step is a solid board for your projects – our Freetronics Eleven – the Arduino-Uno compatible with low-profile USB socket, onboard prototyping space and easy to view LEDs:

Build an Arduino-powered CyberGlove

For a new an interesting method of receiving user input, this “CyberGlove” by Instructables user ‘aloishis89’. Although the concept may seem complex, the construction is surprisingly easy. By using fitting analogue joysticks near the knuckles on the glove, and then wire to the fingertips back to the joysticks, you can easily measure one or two directions of movement with an Arduino’s analogue input. That data can then be fed back to a PC for control via processing, or even mouse/keyboard emulation with an Arduino Leonardo or compatible boards

And the whole thing could be done for less than $100… so click here to get started. And for more, we’re on twitter and Google+, so follow us for news and product updates as well. 

This project is the ideal candidate for our LeoStick – the Arduino Leonardo-compatible board that’s cheaper and smaller than the original:

 Apart from being one of the smallest Arduino-compatibles on the market with USB, it also has an onboard RGB LED and piezo which can be used a knock sensor and various tune and sound effects. Plus you can add extra circuitry with the matching protostick! For more information and to order, click here.

Learn piano with the help of Arduino

Learning to play the piano can be easy for some, difficult for others. However with the device described by Instructables user “tcone”, you’ll not only get started with the piano but also make a fascinating project. It comprises of a long acrylic strip which is placed over and to the rear of the piano keys – that holds an LED over each key. Then the order and timing of each required key press is illustrated via an LED controlled by the Arduino. There’s 88 LEDs so the use of the MAX7219 LED display driver is used, which saves a lot of trouble. Review the following video for a demonstration of the system:

 

Fantastic. With a little work you could also adapt this to organs or harpsichords. For complete instructions on making your own, visit the project page. And for more, we’re on twitter and Google+, so follow us for news and product updates as well.

If you found the project above interesting – but not sure how to start with Arduino – then the best way to learn is with our Experimenter’s Kit for Arduino:

The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit. However we don’t leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words – this is everything you need to get started for a fun range of electronics and Arduino related projects!

Interfacing an Arduino with MySQL via python

If you’re interested in taking data from an Arduino and running it through some hard-core analysis, then a tutorial by Instructables member “mangopeach” will be of interest. They’ve demosntrated how to create a software link between an Arduino connected via USB to a PC and then to MySQL via python to allow data capture and analysis. The tutorial assumes some python knowledge, however code examples are provided for Arduino and python to get you started. 

Great for more permanent installations or laboratory use – and this type of interfacing holds some interesting potential, so visit the Instructable to get started. And for more, we’re on twitter and Google+, so follow us for news and product updates as well.

Liven up car interiors with Arduino and RGB LEDs

Many car enthusiasts enjoy adding extra lights or upgrading the interior bulbs to LEDs, however with the Arduino platform you can enjoy a greater level of control and detail by controlling high-powered LEDs and lighting strips. Doing so is easily done with an external power supply, an N-MOSFET for switching the higher current and a compact Arduino-compatible board such as our LeoStick. Hyundai Veloster enthusiast “Tokra” did just that, by building a system that generates various lighting effects when the car door is opened and closed, for example:

 

What a great way to liven up a car’s interior – find out more at the Veolster forum. And for more, we’re on twitter and Google+, so follow us for news and product updates as well.

If you’re making a similar project and need to control large currents with your Arduino digital outputs – you’ll need a MOSFET. We’ve got you covered with out NDRIVE: N-MOSFET driver/output module:

This high-power N-MOSFET module lets you switch high-current loads using a tiny microcontroller. Perfect for controlling that set of traffic lights mounted in your living room! Works brilliantly for automotive projects such as switching high-power 12V lights and high wattage LEDs. For more information and to order, visit the product page

Build an Arduino-controlled FM radio

Building one’s own radio was often a rite of passage for many electronics enthusiasts, however in the digital age this may have passed to one side as people often start their learning with microcontrollers and of course Arduino-based projects. Nevertheless it’s possible to make your own Arduino-controlled FM radio with the inexpensive Philips TEA5767 tuner IC which is available for a few dollars with a few minutes searching the Internet. This has been demonstrated by Lithuanian enthusiast Darius who explains the I2C commands for the module and an Arduino sketch for a basic radio with LCD module display, with the results as follows:

 

With the addition of a basic audio amplifier a portable solution could be built. Or with anRTC perhaps a clock radio? Visit Darius’ blog to get started. And for more, we’re on twitter and Google+, so follow us for news and product updates as well.

Build a reaction timer game with Arduino

Arduino enthusiast Petri Häkkinen was reminiscing about an older television show that used a form of reaction timer game, and reconstructed his own version based on Arduino hardware. The operation is quite simple – the user needs to press one of four randomly selected buttons within an ever-decreasing period of time. Sooner or later the time allowed will be too short or the player’s reaction time won’t be good enough. Furthermore the game uses distinct musical notes for each button so the game can be played just by listening. A quick demonstration follows in the video below:

 

That could be a lot of fun for children and adults alike, so to make your own find the instructions on Petri’s website. And for more, we’re on twitter and Google+, so follow us for news and product updates as well.

If you’re prototyping Arduino projects on solderless breadboards, blown the MCU on your board, or making your own such as the timer game mentioned above – save time and hassle with our new ATmega328 microcontroller pre-loaded with the Arduino Uno bootloader:

It’s the same one as found on our ElevenKitTen and the original Arduino Uno, plus it has a very useful pinout sticker attached to save confusion when wiring it up. So for more information and to order, click here. And we also sell the stickers!
