Do you just really hate yellow Skittles? Only love the red ones? Well, why waste your time sorting them out yourself when an automated machine can do it for you? As part of a recent tutorial, Dejan Nedelkovski has built what we calls the “Arduino Color Sorter” using a TCS3200 color sensor, two hobbyist servo motors, and an Arduino Nano.
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 […]
While this recent project may look like something straight out of Simone Giertz’s notebook, it’s actually the brainchild of James Cochrane. The engineer, who admittedly loves building all sorts of crazy machines, has developed an apparatus he calls the IoT Robot People/Pet Affectionator. As its name would suggest, the Affectionator is an Arduino Nano-driven device that automatically gives his dog […]
Project-based lessons are a great way to introduce students to the world of electronics. Clearly Jenna Debois agrees, as she has built a DIY classroom clock based on an Arduino Nano. What’s even cooler is that it’s optimized for teachers!
An entry in this year’s Hackaday Prize, Dtto is a snake-like robot designed to be modular and self-reconfigurable. Inspired by Bruce Lee’s famous water quote, Dtto can transform into various shapes by changing the position and connection of its 3D-printed modules. As Hackaday points out, each section of Dtto is a double-hinged joint. When two come together, magnets help them align. A […]
Jochen Maria Weber’s Foxes Like Beacons is an exploratory project using open data of public radio stations with inexpensive, low-power signal detection in order to create an open positioning system. According to the designer: Today’s satellite based GPS enable and augment uncountable everyday processes, ranging from logistics to fitness trackers and even intimate dating applications. These proprietary […]
Back in 2014, Josef Holmner built his own DIY quadcopter with a flight time of 30 minutes. Impressively, he also developed a wearable controller that enabled him to maneuver his device through the air using just one hand. As you can see in the video below, pitch and roll are dictated by the angle of his hand, yaw […]
If you’ve ever wanted to add biometric security features to your Arduino project, you’re in luck. That’s because Nick Koumaris of educ8s.tv has put together a quick tutorial on how to integrate a fingerprint sensor module with an Arduino Nano and a 1.44” color TFT display. The fingerprint sensor module is small, nicely built, and it uses some advanced DSP (Digital […]
Walking the streets of a highly-populated city, or even a crowded event for that matter, comes with certain risks like pickpocketing. Mindful of this, Maker TVMiller has come up with a clever system to prevent bag thieves from unknowingly creeping up behind you. Called the “Arduino MetroPhones,” the device consists of a Nano, an ultrasonic sensor, a digital potentiometer, a coin-cell […]
The Base42 team, which is part of the hacking community Tecnoateneu Vilablareix, has created a stunning water curtain with the help of 3D printing and Arduino. The installation, currently on display at the Temps de Flors flower show in Girona, uses 128 3D-printed nozzles and 64 3D-printed valves to dispense water in floral patterns. The water curtain employs four Arduino Nanos to control the valves, […]
