Centimeter-scale lawn mower positioning without GPS RTK
Reading Time: 2 minutesArduino Team — July 27th, 2022 GPS is perfect for navigating roads, because that doesn’t require much precision. But GPS is only accurate to several meters, which means that it is unsuitable for applications that require more precise positioning. GPS RTK (real-time kinematic) systems can achieve much greater accuracy, but they are…

This walking machine can mosey in any direction
Reading Time: 2 minutesArduino Team — July 27th, 2022 Wheeled vehicles are so common because they’re efficient. If a vehicle will drive on a relatively smooth and flat surface, wheels are the most efficient option. But on rough terrain, wheels don’t always cut it. For such terrain, tank tracks and more exotic options often perform…

This system detects leaks by listening to water flowing through pipes
Reading Time: 2 minutesArduino Team — July 27th, 2022 Damaged, leaking pipes are not only a nuisance to clean up after, but they can also create major inefficiencies within water delivery systems, leading to a loss in both the water itself and the electricity required to disinfect and pump it. Over the past decade, water…

A DIY thermally actuated deformable mirror
Reading Time: 2 minutesArduino Team — July 25th, 2022 In typical applications, the optimal mirror is as flat as possible. The flatter the mirror, the less optical distortion it imparts onto the reflected “image.” Distortion isn’t often desirable, so precision mirror manufacturers take great pains to manufacture ultra-flat mirrors. But distortion is sometimes a good…

Reviving a vintage secondary split-flap clock with Arduino
Reading Time: 2 minutesArduino Team — July 25th, 2022 In the world of computing, many interfaces utilize a primary/secondary model of asymmetric communication, in which a primary host device controls one or more secondary client devices. This model is, for example, common among PATA and SATA hard drive arrangements. It is also common in clock…

Industrial IoT anomaly detection on microcontrollers
Reading Time: 2 minutesArduino Team — July 22nd, 2022 Consumer IoT (Internet of Things) devices provide convenience and the consequences of a failure are minimal. But industrial IoT (IIoT) devices monitor complex and expensive machinery. When that machinery fails, it can cost serious money. For that reason, it is important that technicians get alerts as…

Playing record covers instead of the vinyl
Reading Time: 2 minutesArduino Team — July 21st, 2022 In 2020, for the first time since the ’80s, vinyl records outsold CDs. Digital music — particularly streaming — outpaced both by a wide margin, but the popularity of vinyl records increased while the popularity of CDs decreased. That’s because the analog sound of vinyl adds…

Touch-sensitive steering for a RatCar
Reading Time: 2 minutesArduino Team — July 19th, 2022 Bears on tricycles aside, animals are not very good at piloting vehicles. But maybe that is because we haven’t given them controls that suit their thumbless bodies. If a vehicle had controls adapted to a particular animal’s anatomy, could they drive? Back in 2019, researchers at…
