Built on the basis of Arduino UNO, GPS, SD card, TFT, GPS map navigation system is to obtain the real-time position information via GPS, to send it to UNO for calculation, according to the calculating results, and teamed up with the

map file stored in SD card, thus presenting the position on TFT. The GPS system, owing the function to store the current position information, can be applied to running positioning and to record the running tracing.

The Beach Buddy

When you venture out onto the beach for a day in the sun, you’re probably not preoccupied with remembering the specifics about your sunscreen’s SPF rating—if you even remembered to apply any. [starwisher] suffered a nasty sunburn after baking in the sunlight beyond her sunscreen’s limits. To prevent future suffering, she developed The Beach Buddy: a portable stereo and phone charger with a handy sunburn calculator to warn you the next time the sun is turning you into barbecue.

After telling the Beach Buddy your skin type and your sunscreen’s SPF rating, a UV sensor takes a reading and an Arduino does a quick calculation that determines how long until you should reapply your sunscreen. Who wants to lug around a boring warning box, though?

[starwisher] went to the trouble of crafting a truly useful all-in-one device by modifying this stereo and this charger to fit together in a sleek custom acrylic enclosure. There’s a switch to activate each function—timer, charger, stereo—a slot on the side to house your phone, and an LCD with some accompanying buttons for setting up the UV timer. You can check out a demo of all the Beach Buddy’s features in a video below.

Play the DIY arpeggiator with infrared detectors and Arduino Mega

infraharp

After spending some time on Arduino Forum and finding the right solutions for his project’s sketch, Connor Hubeny shared with us the infraHarp: an Arduino-powered eight-tone arpeggiator made with infrared emitters and detectors, Sparkfun’s Musical Instrument Shield, and an Arduino Mega 2560:

The InfraHarp was my first Arduino project. At first the project seemed daunting since I had no previous experience in programming and electrical engineering. Yet after spending some time with the Arduino I realized that electronics work very much the same, and by learning a few core components you are really right on the doorstep of exploring any technology you have the faintest interest in.

The InfraHarp can play in the keys of A, B, C, D, E, F, G in major, minor melodic and harmonic scales, with two octave choices. Listen to it in the video below:

 

The project requires basic soldering skills and Connor shared all the info and the sketch on this page.

Voice Controlled Lamp

[Saurabh] wanted a quick project to demonstrate how easy it can be to build devices that are voice controlled. His latest Instructable does just that using an Arduino and Visual Basic .Net.

[Saurabh] decided to build a voice controlled lamp. He knew he wanted it to change colors as well as be energy-efficient. It also had to be easy to control. The obvious choice was to use an RGB LED. The LED on its own wouldn’t be very interesting. He needed something to diffuse the light, like a lampshade. [Saurabh] decided to start with an empty glass jar. He filled the jar with gel wax, which provides a nice surface to diffuse the light.

The RGB LED was mounted underneath the jar’s screw-on cover. [Saurabh] soldered a 220 ohm current limiting resistor to each of the three anodes of the LED. A hole was drilled in the cap so he’d have a place to run the wires. The LED was then hooked up to an Arduino Leonardo.

The Arduino sketch has several built-in functions to set all of the colors, and also fade. [Saurabh] then wrote a control interface using Visual Basic .Net. The interface allows you to directly manipulate the lamp, but it also has built-in voice recognition functionality. This allows [Saurabh] to use his voice to change the color of the lamp, turn it off, or initiate a fading routing. You can watch a video demonstration of the voice controls below.

Hacking A Bee Hive

[Marc] created a self-contained monitoring platform that enabled him to record the temperature and humidity of his bee hives.’

The health of colony can be determined based on a few factors. One is temperature which is an early indicator of whether or not the bees are about to swarm. Once temperature spikes are noticed, the bee wrangler can take the necessary steps to reduce the chance of losing the hive to a neighbor. Another indicator of bee health is humidity. If the area is too damp, it can damage the hive.

With that in mind, [Marc] developed a system to alert him via SMS or email if the sensor readings go beyond a certain range. In addition, he monitored the weight of the hive to see how much honey is inside. Frequency of the buzz was also recorded, and so was the activity of the entrance. He used an Arduino Duo and a DHT22 temperature/humidity sensor. A solar panel powered the bee monitoring system.

There were some challenges that needed to be overcome. Initially the Arduino wasn’t sending out data, but that was fixed with a simple debugging session. From there, he was able to broadcast the information creating graphs with the data. Battery levels, temperature, and humidity were all recorded. With the bee hive hacked and monitored, [Marc] was able to make progress on his system making great use of an Arduino.
