While the STAR, or Sprawl Turned Autonomous Robot, is more than capable of traveling over obstacles with its three-pointed wheels, it can also make itself thin enough to simply slide under others as needed. This clever design uses an Arduino Pro Mini for control, and normally moves around like a tank, rolling on six wheels […]

Tell time on a three-module voltmeter clock
Father’s Day 2018 has come and gone, but it’s never too early to start planning for next year. As seen here, Michael Teeuw decided to build a clock out of three analog voltmeters for his dad in 2017. After getting sidetracked last year, he was finally able to complete it on time for 2018! Teeuw’s […]

Track the sun with this Arduino-based solar panel
Solar panels are a great way to produce power literally out of thin air, but how much power they produce depends, in part, on how they are aimed. In order to figure out just how much better his solar setup could be with active tracking, YouTuber GreatScott! decided to test this by creating a miniature […]

Nature and Arduinos combine as binary driftwood alarm clock
Binary clocks, which use a series of dots to indicate the time, are nothing new, but you’ve never seen anything like this device by Matt Wos! Wos’ project features a beautiful driftwood base, and WS2812B RGB LED dots that are suspended above it with copper wire to show the time. Inside are a pair of […]

Novel lathe control method with Arduino
If you want to work with round parts, a lathe is the tool to have, but takes some time to master. A full CNC version takes even more time and skill to understand, but mechanical engineer “Wade’o Design” has come up with something in between. Instead of running his machine with code directly, his device […]

Morse code input for Android with Arduino
Morse code may not be as widely used as in its heyday, but it still certainly has its adherents. One avid user is Tanya Finlayson, who has been using this as her method of communication for roughly 40 years. Now, with the Gboard phone keyboard supporting input via dots and dashes, the world of Android […]

Dual ultrasonic sensors combine for 2D echolocation
Ultrasonic sensors are great tools for measuring linear distance or object presence. As shown in this experiment by “lingib,” two sensors can also be combined to determine not just linear distance to a sensor, but its position in an X/Y plane. For his experiment, he hooked two of these units up to an Arduino Uno at […]

Camera questions user, saves photographic response
Cultural probes aim to elicit unique responses by asking people to respond to a question, many times in the form of a photograph. While disposable cameras once worked quite nicely for this purpose, their relative rarity today meant a new digital alternative was needed. For this, Interaction Research Studio came up with a series of […]

Arduino goes to summer school in Costa Rica!
Back in April, the Arduino team ran a physical computing workshop as part of the summer school program organized by the Copenhagen Institute of Interaction Design. Each workshop was taught in the context of the United Nations Sustainable Development Goals. The one-week long class focused on designing physical and interactive objects that can help kids […]

“Magical” fountain bends time under Arduino control
Years ago, engineer and photographer Harold “Doc” Edgerton figured out how to “bend time” by pulsing a strobe light at the nearly the same speed as droplets of water, making them appear to move in slow motion, freeze, or even more backwards. Today, Nick Lim of jolliFactory has created the same effect, controlled by an […]

An Arduino “Whack-a-Button” Reaction Game
After Instructables user R0RSHACH’s son won a place at the World Scout Jamboree in 2019, the maker decided to create a fairground-style game for fundraising. The resulting device is akin to a Whack-a-Mole or Batak game that can be found at high-end gyms, and features eight large light-up buttons per player on a wooden frame. When activated, […]

imPulse is an energy harvesting alternative for bicycles
Javier Betancor is developing a system that collects power as you ride a bike, with the goal of powering data collection and lighting. “imPulse” uses a stepper motor for power generation, along with a geared hub to make the motor spin at multiples of the wheel speed. While the project is still a prototype, the headlights […]

Stepper motor utilized as a rotary encoder with Arduino
Stepper motors work by alternating a series of magnets in order to rotate its shaft by a certain angle. When the shaft is manually twisted, these magnets produce an electrical signal in a predictable pattern, which as shown in the video below, can be used as an encoder with the help of an Arduino Uno. […]

Ramp up programmable LED troubleshooting with the BlinkBox
Programmable LEDs are amazing pieces of hardware, allowing hackers to add a rainbow of colors to projects at reasonable prices. Troubleshooting these devices, however, can be a pain, so Devon Bray developed the “BlinkBox” to help with this task. The resulting Arduino-based tester can work with multiple types of LEDs, and is able to cycle through […]

Smart hydroponic assembly made with Arduino Mega
If you love electronics as well as plants, what better way to combine the two than with a smart hydroponic system? Students at the Juan de Lanuza School decided to do just that, creating a portable hydroponic assembly that’s automatically controlled with the help of an Arduino Mega. The system uses six lengths of PVC […]

Arduino-Controlled Signal Attenuation
There are many ways to modify analog and digital electrical signals, but things get a bit more complicated—or at least specialized—when working with coaxial signal transmission. To this end, Kerry D. Wong found an unused attenuator evaluation board in his “miscellaneous PCB bin,” and decided to give it a new life using an Arduino. The […]

Ping pong ball bounces forever under Arduino control
As spotted on Reddit, maker “tkuhn” of Electron Dust decided to make a machine “with the sole goal of keeping a ping pong ball bouncing for as long as possible.” To accomplish this, he turned to audio feedback using the time difference between when four electret microphones sense the sound of the bouncing ball. Audio processing […]

Add fading light effects to the buttons on your arcade controller
Making a custom arcade cabinet has become something of a rite of passage for aspiring hackers. As seen here, maker Rodrigo decided to add an extra bit of “flair” to his build (Portuguese), with buttons that light up under Arduino power. As demonstrated in the video below, the button lights slowly fade out after being […]

Single-handed smartwatch text entry with WrisText
Smartwatches can keep us informed of incoming information at a glance, but responding still takes the use of another hand, potentially occupied by other tasks. Researchers at Dartmouth College are trying to change that with their new WrisText system. The device divides the outside of a Ticwatch 2 into six sections of letters, selected by […]

DolphinView headset lets you see the world like Flipper!
Dolphins are not only amazing swimmers and extremely intelligent, but can also navigate their surroundings using echolocation. While extremely useful in murky water, Andrew Thaler decided to make a device that would enable him to observe his (normally dry) environment with a similar distance-indicating audio setup. While he first considered using an ultrasonic sensor, he eventually […]
