Combining a spirit level and range measurer into a single device

Combining a spirit level and range measurer into a single device

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.

ZIPY is a homebrew inverted pendulum

ZIPY is a homebrew inverted pendulum

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.

The MKR family gets bigger with two new IoT boards!

The MKR family gets bigger with two new IoT boards!

We’re excited to announce two new wireless connectivity boards to help streamline Internet of Things development, the MKR WiFi 1010 and MKR NB 1500.

The first of the boards is the MKR WiFi 1010which offers low power consumption and has been designed not only to speed up and simplify the prototyping of WiFi-based IoT applications, but also to be embedded in production IoT applications that require WiFi connectivity.

MP3 player “reads” CDs like a vintage Victrola

MP3 player “reads” CDs like a vintage Victrola

Digital music—which gives us access to a virtually unlimited amount of media at our fingertips—is an amazing innovation. On the other hand, if you get nostalgic for something a bit more tangible, this “Victrola for the 21st century” may just fill that gap.

Meet Eve, the Arduino chatterbot

Meet Eve, the Arduino chatterbot

If you ever find yourself needing someone to talk to and can’t find a confidant—or perhaps even a pet—then the Eve chatbot by Debashish Buragohain will happily fill in.

This little robot uses Google Voice Recognition on an Android phone to listen to what you say and convert it to text, then pipes it over to the Arduino-based robot via Bluetooth.

Control your computer sheet music with the PartitionsDuino

Control your computer sheet music with the PartitionsDuino

Performing an instrument well is hard enough, but flipping through sheet music while playing can slightly delay things in the best case, or can cause you to lose your concentration altogether. Music displayed on a computer is a similar story; however, Maxime Boudreau has a great solution using an Arduino Nano inside of a 3D-printed pedal assembly.
