Coisas do Arduino- Designing an extremely realistic animatronic heart with ArduinoIn his latest video, Will Cogley has created an animatronic heart so realistic that you might wonder if it’s the actual thing. The device is made out of molded silicon with fake blood poured on top to enhance the effect, and inside a trio of servo motors push the lower and upper sections of the […]
- Pick colors from real things with this portable toolIf you want a red piece of paper, or a blue pen, what does that really mean? If you’d like to get more specific, Michael Klements’ Arduino-based scanner lets you quantify colors in numerical RGB values via a TCS34725 sensor. User interface for the handheld device is extremely simple, with a single button to trigger […]
- Aarnio adds force feedback and sensing to chairsDesk chairs are essential tools for the office environment, so why not turn them into a computer input and feedback device? Aarnio, by researchers from several universities, adds this functionality via an Arduino board. It’s able to detect rotation and tilt via an MPU-6050 IMU, and how far it travels along the floor with an […]
- Upgrading a ride-on car to a joystick-controlled assistive deviceChild-sized wheelchairs can be difficult to come by, and unfortunately aren’t as much fun as something like a ride-on car. The South Eugene Robotics Team, or FRC2521, decided to address both challenges by building a mini Jeep augmented for kids with limited mobility. Instructions found here detail how to modify the battery-powered toy, including what […]
- Scale model Oldsmobile Dynamic 88 wagon handles like the real thingModel cars can be fun to use and look at, but when driving one it’s difficult to get the same sort of movement in the suspension as a full-sized vehicle. To enhance his 65cm long 8.5:1 Oldsmobile Dynamic 88, creator Dimitar Tilev turned to an active suspension system controlled by four micro servo motors. When […]
- Arduino goes PRO at CES 2020We’re kicking off this year’s CES with some big news. Millions of users and thousands of companies across the world already use Arduino as an innovation platform, which is why we have drawn on this experience to enable enterprises to quickly and securely connect remote sensors to business logic within one simple IoT application development […]
- Adaptive Field Robot changes wheel shape to overcome various terrainIf your robotic vehicle will only work on smooth surfaces, the choice of a wheel is obvious. For more rugged bots, the same applies with knobby wheels. For those that need to operate in both environments, however, the Adaptive Field Robot presents a new solution in the form of wheels that actually change dynamically depending […]
- Hundreds of LED triangles combine for brilliant interactive displayIf you need another idea for how to creatively diffuse LED lighting, then look no further than the “Light Me Up!” project by Hyewon Shin, Eunjeong Ko, and Junsung Yi. Their setup uses 312 3D-printed and laser-cut light triangles, each of which contains a trio of RGB LEDs. Users select the desired light by pressing […]
- Will Cogley’s tester controls 16 servos simultaneouslyWhen you need to test a single servo, it’s a fairly straightforward task. Just hook it up to an Arduino to generate the proper PWM signal, along with an appropriate power supply, and you’re in business. If, however, you need to test a bunch of them at the same time, things get a bit more […]
- Designing a two-axis gesture-controlled platform for DSLR camerasHolding your phone up to take an occasional picture is no big deal, but for professional photographers who often need to manipulate heavier gear for hours on end, this can actually be quite tiring. With this in mind, Cornell University students Kunpeng Huang, Xinyi Yang, and Siqi Qian designed a two-axis gesture-controlled camera platform for […]
