Play beautiful music on an Arduino thumb piano

Arduino Team September 29, 2016

With an accelerometer and capacitive sensing, even a beginner can produce some great tunes with this DIY device.

If you like making beautiful music, but would rather not actually practice this skill, perhaps this thumb piano and controller by producer/DJ Rob Blazey would be a good instrument to pick up. His project, called “Kalimbo,” employs an Arduino to translate manipulations of metal rods, along with movement of the piano itself, into Open Sound Control (OSC) messages. These are then be used to produce music. Read the rest of this entry »

A multimeter heads-up display with Arduino glasses

Arduino Team September 29, 2016

With Alain Mauer’s Arduino glasses and a Bluetooth multimeter, electrical data is always in view!

If you’re in a job where you have to take readings inside a live electrical panel, one thing that’s inconvenient, and even dangerous at times, is having to look away from your hands to read your multimeter. With hopes of “making an engineer’s life easier and safer,” Mauer solved this problem using an Arduino Pro Micro and a BLE module to show data from a Bluetooth-enabled multimeter. Now he can see data on a display that looks similar to a Google Glass device. Perhaps this method could be expanded to other devices in the future!

Robotic fish swims under Arduino control

Arduino Team September 29, 2016

This robotic fish is made from bent PVC pipe and moves its tail for locomotion.

If you’re going to build an underwater vehicle, propeller control is the conventional solution. Eric Dirgahayu, however, created his underwater creature in the form of a fish, complete with a tail that powers it through the water, and pectoral fins that could, in theory, steer it in the correct direction. There is also a ballast tank to adjust its buoyancy. Interestingly, control of this “fish” is accomplished via a TV remote, so the surrounding water would need to be relatively clear.

ESLOV is the amazing new IoT invention kit from Arduino

Arduino Team September 28, 2016

For years, the open-source philosophy of Arduino has been the inspiration to robots, drones, medical and space research, interactive art, musical instruments, 3D printers, and so much more. Now, Arduino is on a mission to radically simplify the way you build smart devices. Introducing ESLOV, a revolutionary plug-and-play IoT invention kit.

ESLOV consists of intelligent modules that join together to create projects in minutes with no prior hardware or programming knowledge necessary. Just connect the modules using cables or mounting them on the back of our WiFi and motion hub. When done, plug the hub into your PC.

ESLOV’s visual code editor automatically recognizes each module, displaying them on your screen. Draw the connections between the modules on the editor, and watch your project come to life. From there, publish your device to the Arduino Cloud and interact with it remotely from anywhere (including your phone). The Arduino Cloud’s user-friendly interface simplifies complex interactions with sliders, buttons, value fields, and more.

The ESLOV modules and hub can also be programmed with the wildly popular Arduino Editor — you can use either the online editor or the desktop-based IDE. With the provided libraries, you can customize the behavior of the existing modules, enhance the hub’s functionalities, as well as modify the protocols of both the hub and the modules.

Building a sweet plastic MIDI controller

Arduino Team September 26, 2016

With parts from a bathroom organizer and arcade buttons, Alex “GlacialGeyser” made his own MIDI machine.

MIDI controllers can be great instruments to supplement your musical skills. As seen in the video below, Alex’s project is no exception, and he’s able to produce some really beautiful music using it and a keyboard. Physically, he created this out of plastic parts from a bathroom organizer and a cutting board that he cut using mostly handheld power tools. An Arduino Mega serves as the brains of the operation along with two 75mm 10k faders, two 10k knobs, pitch bend and modulation wheels, and a couple of LEDs.

The build is finished off with a splattered paint effect and nearly a whole can of clear coat. Programming the device was a challenge, but it seems Alex gained some useful knowledge for next time! Read the rest of this entry »

A DIY interactive book that uses digital gestures

Arduino Team September 26, 2016

taz-inter

Digital and craft maker lab Tazas recently worked with a group of master students on an interactive book/prototype to reflect on how gestures like swiping have become as natural as shaking hands. Digital Gestures is a metaphor of the human body’s physiological senses, which identifies 10 actions inherent to our daily interactions with technology: drag and drop, spread and squeeze, swipe, double tap, scroll, zoom, rotate, draw, press, press and hold.

HAL 9000 reimagined as a useless machine

Arduino Team September 23, 2016

GeekCon participants add a switch and actuator to a HAL 9000 model for the world’s largest “leave-me-alone box.”

You’ve probably seen the silly boxes that when you flip a switch to turn it “on,” an arm comes out to turn itself “off” again. At this year’s GeekCon Makers conference, participants decided to make a useless machine, but in place of a simple box, they made a model of the HAL 9000 computer from 2001: A Space Odyssey.

Rather than the normal “useless” configuration, it turns itself “on” instead of “off” in an apparent nod to the fact that the computer didn’t want to be disconnected in the movie. One Arduino controls a projector for the “eye” assembly, while another takes care of the servos and audio. HAL’s sounds are stored on an SD card inside an Adafruit Music Shield.

An Arduino VU meter for classrooms

Arduino Team September 23, 2016

With his beautifully-colored classroom “noise-o-meter,” Mr. Jones knows when things are getting out of hand.

When you were in school (or if you are in school) the teacher likely told the class to be quiet, perhaps repeating him or herself over an over during the day. The teacher, however, likely never really defined what is good and bad. Mr. Jones has finally solved this issue by creating a classroom “noise-o-meter” using an Arduino, an electret microphone, and a programmable LED strip. In order (apparently) too keep the class in line, noise is simply marked as green for “expected,” amber for “louder,” and “red” for too loud which corresponds nicely with more “traditional” VU meters.

Build your own robotic vacuum from scratch

Arduino Team September 23, 2016

This dust buster-based robotic vacuum may or may not work as well as a Roomba.

If you’re fascinated by the idea of a robotic vaccum cleaner to keep you from having to do certain chores, you could buy an iRobot, or you could make your own instead. This particular DIY model uses four motors for locomotion, an Arduino Uno, IR and ultrasonic sensors to avoid obstacles, as well as a (formerly) handheld vacuum cleaner to suck up debris.

The assembly sits on a wooden chassis, and as author B. Aswinth Raj is quick to point out, many variations on this robot could be made. Code is included and fairly short, so whether you’d like to copy this design or improve upon it, the bot should certainly give you some build ideas! Read the rest of this entry »

An animatronic talking takeout container

Arduino Team September 22, 2016

An Arduino plus fake food and audio capabilities equals something truly unique!

Randy “randofo” Sarafan had an idea when he was in college: a takeout container that talked. To the world’s great benefit, now that he knows about electronics, he finally made this dream a reality. Using an Arduino Mega with a Seed Studio Music Shield, he was able to coordinate the movements of a servo and thus the lid of a box with the audio coming out of a speaker. After attaching googly, or “googily” eyes, and modifying a fake serving of spaghetti, he had something that should be quite entertaining! Read the rest of this entry »
