This article was written by Per Tillisch, Tooling Team SW Engineer at Arduino. The Arduino team created a tool to check Arduino projects for common problems. Arduino Lint runs over 175 checks on your sketches, libraries, and boards platforms which cover specification compliance, Library Manager submission requirements, and best practices. Arduino Lint Arduino Lint is

As a unique way to “pop the question” to their girlfriend, Redditor lmjd14 created a scavenger hunt for the proposal using a sequence of Arduino-based puzzle boxes. The first box opens when one inputs a series of codes on a keypad, which relate to important relationship dates, while the second responds to holding down the

As we all know, when aliens descend from outer space, they often beam bovine up for testing and observation. While you might not have the privilege of seeing this process in action, “OneldMONstr” has created the next best thing: a miniature model of a cow being beamed up, complete with smoke and lighting effects. The device features

How many times a day do you grab your phone for trivial purposes, such as scrolling through social media? Nick O’Hara found that his number was around 100 times during the workday, which sounds like a lot, but is likely pretty typical. To combat these micro-distractions, he built an Arduino-based device that senses when a phone is

As reported by Hackaday, fishing is generally considered to be a fun and relaxing activity, but it isn’t accessible for those without a certain amount of strength and dexterity. To help more people to be able to enjoy this sport, Ozgur Ozcan has been working on what he calls the “FISHBOT.” This auto-fishing device is controlled

After welcoming a new child into the world, Mike Buss decided that his 3D printer needed a few safety enhancements. To address this issue, he added a clear chamber on top of his Ultimaker S3 with a fan and filter to remove volatile organic chemicals (VOCs), controlled by an Arduino Nano 33 IoT. The Nano 33

As noted in Peter Turczak’s project write-up, having a kitchen hood only works when it’s turned on. To avoid having his apartment constantly smell like “appetizers,” the hacker hooked up an Arduino-based system to trigger it automatically. The setup senses power input to the stove using a current transformer, processing this input with an Arduino Nano. The Nano

Tic-tac-toe is normally played with a pen and paper, or perhaps with a physical marker, but maker “techiesms” has put a new spin on this classic pastime. His build, as seen here, features a wooden box that mounts onto the wall with nine square sections arranged in a grid pattern. Players take turns, activating a square

After observing a bicycle chain lying on the street in a random pattern, Ekaggrat Singh Kalsi was inspired to make a morphing clock that bends chains to tell time. The clock, known as “GETULA,” consists of four independent modules that work together to reveal the hour and minutes. Each GETULA module uses two stepper motors to

If you don’t enjoy sorting LEGO, you will be pleased to know that students at Bruface – or the Brussels Faculty of Engineering in Belgium – are working on an automated machine to do it for you! The team’s prototype device detects brick colors on a conveyor belt and picks them up via a gantry-style
