Riding a bike can be great exercise, but unless you have access to a velodrome, when the weather turns bad, training is interrupted. There are of course training wheel setups that you can use to simulate riding indoors, but without the stimulus of actually moving, things can get boring rather quickly. The Infinity Bike by Alexandre […]
Tired of wondering what time it is at night, only to have to roll over to look at your alarm clock? If you’d like to avoid this nighttime inconvenience, then Kurt Andros has a great solution with his Arduino Mega-based Overhead Alarm Clock. The device consists of a nice wooden housing that gets mounted to […]
Ukuleles can be a lot of fun to play, and since cheap yet very playable versions can be had for under $50, they make a great target for hacking. And what better way to decorate an instrument by adding LEDs? Elaine Chow did just that to her uke, adding six LEDs in the fingerboard along […]
This device by Dejan Nedelkovski of How To Mechatronics implements both an ultrasonic sensor for range measurement and an accelerometer for measuring angles. While you’ve likely seen these implemented separately in other projects, combining them saves space, and allows the Arduino Nano onboard to use the two readings together to calculate a square area automatically. […]
If you have young kids, you’ve probably realized that they don’t exactly like to sleep in. While their energy levels are enviable, if their clock-reading skills haven’t yet caught up, this device by maker “JonathonT” looks like a great and simple solution. With help from an Arduino and an RTC module, Jonathon uses a trio […]
Graduate students Ben Wiener and Philip Zucker have been working on a classic controls problem for quite some time called an “inverted pendulum.” This type of device balances a stick on an axis, and in this implementation, a motor pulls the axis assembly that the pendulum—a paint stirrer—is sitting on to keep it stable. Control […]
Farmers have long been known for their ingenuity, able to accomplish urgent repairs with whatever is on hand. Now with the help of an Arduino, maker “rscholten” has even figured out how to automate his chicken coop. The device uses an Uno and a real-time clock module to schedule his automated coop door’s movement, while […]
We’re excited to kick off Maker Faire Bay Area by expanding our IoT lineup with two new boards: the MKR Vidor 4000 and the Uno WiFi Rev 2. The MKR Vidor 4000 is the first-ever Arduino based on an FPGA chip, equipped with a SAM D21 microcontroller, a u-blox Nina W102 WiFi module, and an […]
If you need a way to restrict access to power tools to only authorized users, Casey Horton’s magnetic card reader setup, shown in the video below, looks like a great solution. When you swipe the correct card through a reader mounted on an 8”x8”x4” electrical enclosure, the Arduino Uno inside turns on power to the equipment […]
As seen here, “Annaane!” has come up with what could form the guts of a very interesting escape room puzzle. Her build features four RFID card readers, which cause an Arduino Uno to release a door lock or other device via a 5V relay, only when the corresponding tags are arranged correctly. From the looks […]
