LEDs, whether single-color or programmable, have enabled makers to create a wide variety of vibrant projects at a reasonable price. Neon sign projects, which require sophisticated glass making techniques as well as high voltage for control aren’t as common, but do still have their adherents. Some have even experimented with making them sound reactive.
Up until now, sound control meant using a microphone to detect audio signals and flash accordingly. David Garges, however, is using an Arduino Leonardo equipped with an Olimex MIDI shield to individually activate three neon skulls, crafted by artist Dani Bonnet.
His setup can be programmed via MIDI directly, or can use beat analysis software to activate the proper lights depending on audio output.
There has been much desire in the Neon Art community for clean and responsive musical interaction with high-voltage Neon Signs. Currently, the existing infrastructure uses a microphone to detect audio and flash accordingly. Unfortunately, due to this method of processing the Neon always responds with a small delay. Clapping and shouting can also disrupt the interaction when using an on-board microphone.
This project solves that problem by transmitting musical data via MIDI protocol to a controller which activates then activates Neon Tubes accordingly. I have designed and built a system that takes a slightly different approach but accomplishes what the Neon Art community desires.
This project offers two performance modes: one that allows for electronic artists to perform seamlessly using MIDI instruments, and one that allows DJs to feed BPM analysis to the system to synchronize the Neon flashing with actual recorded music which enables Real-Time Audio-Controlled Neon.

A little less than a month ago, I joined Arduino as their Chief Information Security Officer. I’ve been in touch with the team for the past couple of months and feel incredibly lucky to be part of such a talented and driven group of people.
We’re working hard on developing a robust, well-rounded security program that fits our organisation and busy improving our security posture across all departments. I am a true believer that it all starts from introducing a strong culture of security awareness — where employees feel confident and empowered to take action against security issues.
Today, I’m thrilled to announce the first release of Arduino’s Coordinated Vulnerability Disclosure (CVD) Policy.
We used some great references when putting it together and we’d like to give them a shout out here: HackerOne’s VDP guidelines, CEPS’ report on “Software Vulnerability Disclosure in Europe,” and the US DoJ Cyber Security unit’s VDP framework. We also took into consideration recent Senate testimony of experts in vulnerability disclosure in the role hackers can play in strengthening security, Dropbox’s announcement on protecting researchers and 18F’s own policy. I even wanted to publicly thank Amit Elazari Bar On, a doctoral law candidate (J.S.D.) at UC Berkeley School of Law and a Lecturer at UC Berkeley School of Information Master in Cybersecurity program for her useful advices and for providing the amazing “#legalbugbounty” standardisation project.
We’re also happy to announce that all of the text in our policy is a freely copyable template. We’ve done this because we’d like to see others take a similar approach. We’ve put some effort in to this across our teams and if you like what you see, please use it. Similarly, if you have improvements to suggest, we’d love to hear from you.
What is CVD?
Coordinated vulnerability disclosure (CVD) is a process aimed at mitigating/eradicating the potential negative impacts of vulnerabilities. It can be defined as “the process of gathering information from vulnerability finders, coordinating the sharing of that information between relevant stakeholders, and disclosing the existence of vulnerabilities and their mitigation to various stakeholders, including the public.”

Electronic keyboards have been around for many years, taking human input and translating it into a variety of sounds. In a strange twist on this technology, Igor Angst has decided to substitute a robot in to push the synthesizer’s keys, using a laser-cut finger setup controlled by an Arduino Uno.
The MIDI sequence/notes to be played are supplied by a computer running ALSA (Advanced Linux Sound Architecture), and interpreted by a C program that translates it into USB serial signals that the Uno can use. It then actuates its wooden fingers, producing a pleasing tune along with apparently keyboard-provided accompaniment in the video below.
I really like the crappy sound of those ‘80s toy keyboards. Unfortunately, I am a lousy live keyboarder and I only have so many hands. So I thought about adding MIDI capability to my good old Casio SA-21. The simplest way to do this is obviously building a robotized hand with 8 servo motors controlled by an Arduino microcontroller, which in turn receives its commands through the serial-over-USB interface sent by a tiny C application that connects to the ALSA sequencer world of my Linux live music setup.

In the middle of a project, you may find that what you’re making is similar to something that’s been done before. Such was the case with Adrian Lindermann when he started constructing his “Twinky” robot and found the Jibo social bot had a similar design.
Like any good hacker, he pressed ahead with his build, creating a small yellow companion that can respond to voice commands via a SpeakUp click module, along with pressure on its face/touchscreen.
Control is provided by an Arduino Mega, and Twinky can interact with other devices using a Bluetooth module. The robot’s head can even turn in order to point the display in the needed direction, and it’s able to play sound through an audio amplifier and speaker.
IT CAN SPEAK! PLAY MUSIC, SET TIMERS, ALARMS, TURN ON/OFF THE LIGHTS OR OTHER APPLIANCES. IT HAS A CALCULATOR AND A WEATHER STATION! DATE & TIME, BLUETOOTH 4.0, EVERYTHING WITH VOICE COMMANDS!!! And also with a touchscreen, it has one little motor so it can turn around when one of the two microphones hear you talk or make a noise.
Author: Arduino Team
After realizing that asking his kids to keep the noise down was meaningless without some sort of standard, maker Jeremy S. Cook decided to construct the “Hello Light.”
This cylindrical device measures sound with an electret microphone and an Arduino Nano, then commands a set of RGBW lights to progressively light up depending on the noise level.
In the end, the Hello Light eventually ended up as more of a game to see who could trigger the flashing volume limit warning—not particularly effective for its intended purpose. It does, however, make a fun interactive decoration, and also features a random lighting mode, and a slowly blinking white light setting.
Code for the project is available on GitHub, and the build process can be seen in the clip below.

You’re constantly poking and prodding your smartphone throughout the day, but have you ever wondered what would happen if this little computer could poke back? Well now that’s actually possible, with the MobiLimb accessory by Marc Teyssier and a team stretching across two universities in France.
The device uses an Arduino to interface with the phone or other smart device via its micro USB port, and powers a servo-actuated robotic manipulator with five degrees of freedom. The servos give the artificial finger enough power to pull the phone itself across the ground, and for other interactions like acting as a physical avatar, propping the phone up as a stand, or even taking input as a joystick apparatus.
MobiLimb is a new shape-changing component with a compact form factor that can be deployed on mobile devices. It is a small 5 DoF serial robotic manipulator that can be easily added to (or removed from) existing mobile devices (smartphone, tablet). In the spirit of human augmentation, which aims at overcoming human body limitations by using robotic devices, our approach aims at overcoming mobile device limitations (static, passive, motionless) by using a robotic limb.
This approach preserves the form factor of mobile devices and the efficiency of their I/O capabilities while introducing new ones:
- The users can manipulate and deform the robotic device (input)
- They can see and feel it (visual and haptic feedback), including when its shape is dynamically modified by the mobile device.
- As a robotic manipulator, it can support additional modular elements (LED, shells, proximity sensors).
More info is available in Teyssier’s write-up, and you can see it in action in the video below.

At Jason Poel Smith’s local pediatrician’s office, they have a variety of movie posters and displays to help make the environment more welcoming to kids. The most popular of them all is a huge inflatable Baymax robot character from the Disney movie Big Hero 6.
While a beautiful display, Smith decided that what would make it even better is if it could talk, and went to work adding this functionality with an Arduino Uno, an MP3 shield, and a very large button.
Now when kids arrive, they can hit the button to hear Baymax welcome them to the office as their “personal healthcare companion” via a pair of powered speakers.
Arduino code and more info is available here, if you’d like to build something similar!

When piloting a vehicle remotely, it’s only natural to tilt your controller one way or the other to “help” guide it in the right direction. While usually this has no effect whatsoever, YouTuber Electronoobs decided to take this concept and run with it, creating a remote control transmitter that responds to an onboard MPU-6050 inertial measurement unit.
The transmitter’s Arduino Nano takes movement data, and sends the corresponding signals to a custom receiver board on the RC car via a pair of HC-12 wireless modules. A second Arduino mounted in the car then commands the vehicle’s DC motors with the help of an H-bridge.
This is a radio controller that has 2 analog channels and the data is out from a MPU-6050 gyro module. So, we could control a toy car for example just by rotating the controller. I usually use the nRF24 module, but in this project I also want to show you how to use the HC-12 module. You will learn how to get the IMU data, how to use the HC-12 radio connection and how to control 2 DC motors using PWM signals and an H-bridge.
It’s quite a versatile build, and it can even be set up to output PWM signals if you need to interface with more advanced electronics.
