Selectively silence a landline phone with Arduino

Wednesday, March 22nd, 2017

Silencing a smartphone at night isn’t difficult, but if you have a landline, Arduino can help!

Before computer hacking/modding became accessible, the next best thing was to creatively explore the phone system via custom electronics. Though this pursuit, known as “phone phreaking,” has largely gone away, some people still have landlines. As “MolecularD” shows in this Instructables writeup, with a few components you can creatively trick your phone into not ringing on your end, while appearing to the caller to simply ring and ring as if no one is home.

In order to make it much more useful, MolecularD hooked up an Arduino Mega with a real-time clock module to turn the device on and off depending on the time of day. Now calls from phone solicitors, or “IRS agents” at 4 in the morning can be eliminated automatically. As noted, this may or may not be legal where you live, so attempt it at your own risk!

Arduino Day: Extended deadline, new events, and more updates!

Friday, March 10th, 2017

ArduinoDay2017_blogpost_NewDeadline-2

Arduino Day is now less than three weeks away, and we cannot wait to celebrate with everyone on April 1st. So far, we’ve received hundreds of submission from all across the world and are constantly updating our map with new events — which by the way, if yours has been approved, do not forget to add the agenda!

As we prepare for Arduino Day, we’ve got three more announcements to share:  

  • NEW DEADLINE: The call for submissions has been extended until March 18th! Remember, participation is open to everyone and anyone can organize event of their own Submit yours here!
  • OFFICIAL ARDUINO DAY IN MALMÖ: Aside from our festivities in Turin, the Arduino team will host another official event in Malmö. The program will include a showcase of Maker projects, free activities for kids, and a lineup of talks. Live in Sweden or nearby? Join us!
  • ONLINE EVENTS: Not only will the Arduino community come together at various physical locations throughout the globe, but now several celebrations this year will also be taking place virtually. If you want to host an online event — such as a hangout or a live streamed workshop (we are very open!) — please contact arduinoday2017@arduino.cc with your idea, and we’ll get back to you!

Last but not least, be sure to post and invite your friends via social media using the hashtag #ArduinoD17

An Arduino VU meter for classrooms

Friday, September 23rd, 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.

Maker builds feeding machine that lets his cat ‘hunt’ for food

Monday, August 8th, 2016

Although automated pet feeders seem to be a dime a dozen these days, Benjamin Millam’s project is on a whole ‘nother level. Last year, the Maker created a system that caters to the primal instincts of his indoor cat, Monkey, by training him to look for plastic balls hidden around the house and then drop them into the machine. Once the apparatus recognizes the RFID-tagged balls, food gets dispensed into the bowl.

The system is comprised of a modified Super Feeder, an Adafruit RFID reader, a remote antenna, a few relays and an Arduino Uno. Millam writes that he conceived the idea after learning why cats repeatedly scour the same area. (more…)

Spinphony turns cycling into music

Friday, July 22nd, 2016

Spinphony is a bike installation that was built in collaboration with 72andSunny‘s Google team and their Made with Code initiative, with hopes of inspiring teenage girls to take an interest in coding.

As its name would suggest, the project combines spinning (indoor cycling) and music with each bike representing a different instrument stem of a song.

For instance, bike one controls drums, bike two might control bass and so on. The way we made it all come together was to have the volume of each stem depend on the speed at which the bike was being pedaled (i.e. the slower the RPM the quieter the stem of the song and vice versa). This is where Arduino came into play.

The prototype is based on an Arduino Uno and uses two magnets, a reed switch, RPM values, and MIDI to produce some spincredible sounds. You can see it in action below!

 

The CALEIDUINO is a digital and sound reactive kaleidoscope

Tuesday, June 28th, 2016

The CALEIDUINO is an Arduino-based digital and sound reactive kaleidoscope, designed to serve as a toy, an art object, and a tool for teaching electronics and programming in a playful yet creative way.

At the heart of CALEIDUINO is a PCB for connecting an Arduino Nano, a TFT 1.8 “display, an analog 3-axis accelerometer GY-61, a piezoelectric, a switch, and a 9V battery–all of which are housed inside a hexagonal methacrylate case. Just like in any kaleidoscope, t three mirrors in triangular prism shape, while an accelerometer collects a user’s movement to generate the psychedelic graphics and sounds.

Sci-fi masks glow to reflect Twitter sustainability trends

Monday, May 9th, 2016

Twitter is not only a convenient way to consume daily news and converse with friends online, it has become an excellent platform for gaining insight on what’s important at any particular moment in time. With this in mind, Maker Chadwick John Friedman has decided to harness the social network’s data into web-connected physical representations with the help of Arduino and Temboo.

PrecogNation uses three 3D-printed geometric masks as real-time sci-fi future forecasters, which illuminate and change colors to reflect sustainability trends throughout the world. (more…)

Arduino and Genuino 101 Available in the Arduino Stores

Thursday, December 17th, 2015

ABX00005_ContextWeb

We’re very excited to announce that starting today Arduino 101* (USA only) and Genuino 101 (Outside USA) made in collaboration with Intel, are available for purchase exclusively on the Arduino Stores at the price of $30/€28,65 (+ tax).

Arduino 101 and Genuino 101 are the ideal successor of the Uno featuring a 32-bit Intel® Quark™ microcontroller for minimal power consumption, 384 kB of flash memory, 80 kB of SRAM (24 kB available for sketches), an integrated DSP sensor hub, Bluetooth Low Energy radio, and 6-axis combo sensor with accelerometer and gyroscope. You’ll be able to create projects with great features like recognising gestures and controlling your phone over Bluetooth connectivity — all without needing additional hardware.

We presented it and gave a preview during Maker Faire Rome 2015: watch Massimo Banzi and Josh Walden Senior Vice President of Intel Corporation introducing the board at the Faire in the video below. (more…)

Node.js on the Arduino Yún via the Bridge library

Monday, July 7th, 2014

ArduinoYun

Tom Igoe some days ago wrote an interesting post about Arduino Yún on his blog.  We post it here as it could be useful to the Arduino Community.

————————–

Recently, Federico Fissore added node.js to the package repository for the Arduino Yún. Here’s how you get node to communicate with the Arduino processor on the Yún via the Bridge library.

To do this, you’ll need an Arduino Yún, a microSD card, a microUSB cable and a wifi connection. You should be familiar with the basics of the Arduino Yún and node.js in order to get the most out of this post.

All of the code for this post can be found on my GitHub repository. (more…)
