This DIY sonar glove can 'feel' distant objects underwater

If you live in a relatively dry climate, you probably don't worry about underwater hazards during the flood season. If you attend Tsukuba University, Japan however -- just miles from where the Kinugawa River flooded Joso City earlier this year -- the risk of rising water is a very real threat. Enough so that two Tsukuba Ph.D. candidates have developed a 3D-printed sonar glove specifically for the purpose of searching flood waters.

Arduino code - switch statement

Hi, I code a program for my autonomous robot. I am sending numbers from 0 to 8 from Raspberry pi to Arduino through Serial communication. I have Rasp code. But arduino code has some problems. Please can you tell me how to write it best? I want to use switch statement to choose direction for my robot/motors. But when I compile that code to arduino on robot - my robot start doing only default commands. Please why????

Arduino uploading issue?

Dear: LMR

Just to let you know I am trying to upload code to my arduino uno but I keep running into this error every time I do so. Can someone please help me I don't think this is anything to do with my code I'm trying to upload? Thank you.

What does it do?

Modified RC obstacle avoidance Car

Very new to this site. Been playing with this project on and off for 6 months. Completed once then went back to and it wasn't working. Tried to troubleshoot and burnt out the chip. Pulled out the whole circuit board. Then rewired the battery pack. At that point it is just the frame DC motors on front and back(front geared to turn right and left, back left as dc motor for fowards and back) . I pulled an H bridge chip from a motor drive expansion board and breadboarded it .

A rec&play loop station for little musicians

The Interaction Awards  published the shortlisted projects for 2016 and up to five finalists in each category will be announced during the event on Friday evening, March 4, 2016. In the Expressing category, showcasing projects enabling self expression and/or creativity there is a project called Step representing an innovative and engaging way of approaching music production for children between 6 and 100 years old.

Step runs on an Arduino and has been created by Federico Lameri, Sandro Pianetti at the Master of Advanced Studies in Interaction Design in Lugano under the supervision of Massimo Banzi and Giorgio Olivero of Todo.

To prototype the user experience we’ve used an Arduino Leonardo connected to a processing sketch that handle the recording and playback features. Using a Mux Shield 2 we managed connecting 25 IR sensors, 16 LEDs, 1 knob and a button to a single Arduino board. We needed a quick and effective way to test the experience and by using Arduino we managed to design and build the whole product in three weeks.

Most of the music toys on the market are trying to fake the sounds and the experience of real instruments. Step has a different approach as it’s designed to give children the opportunity to create real loops and beats using whatever sounds they like from objects of everyday life.

Players can record any sounds and match them with  coloured tags, and then  create melodies, loops and and beats by placing tags on the track and by adjusting the tempo!
