How to Set Up an Ultrasonic Range Finder on an Arduino

Ultrasonic range finders are fun little modules that measure distance. You can use them to find the distance to an object, or to detect when something is near the sensor like a motion detector. They’re ideal for projects involving navigation, object avoidance, and home security. Because they use sound to measure distance, they work just as well in the dark as they do in the light. The ultrasonic range finde ...

RGB LED Cube with Sound to Light Capabilities

The objective of our final project was to build a 5x5x5 RGB LED cube that can display a certain color depending on the frequency of music playing. There are two main components of this project. [gallery columns="2" size="medium" ids="31240,31241"] The first part is the hardware setup that consists of the LED cube and the circuits that drive the power for each LED which is controlled through an Arduino Uno m ...

Electronic Piano

In this project, we will learn how to use an Active Buzzer and a 4Duino to create an Electronic Piano. An active buzzer is an electric piezo device which is commonly used to produce sound. When subjected to an alternating electric field, a piezo ceramic material disc inside the buzzer is caused to stretch or compress, in accordance with the frequency of the signal thereby producing sound. Buzzers are widely ...

An S/PDIF Sound Card Using PCM2906

When S/PDIF became available in the Teensy Audio Library I thought this might be the solution to ground loop problems I’d been having when interfacing projects to my PC. However, I quickly realized I didn’t have any sound cards with an S/PDIF interface. In the belief that I’d rather build than buy I decided to update one of my previous projects, a PCM2904 based sound card, to include an S/PDIF interface. Th ...

Making sound (noise) machines using Arduino

As a part of being an artist in residence at Instructables, I took it upon myself to build of couple of noise machines / music boxes. My interest lies in designing objects that would enable people to explore the world of sound synthesis and for me to get a better understanding on how the different interfaces enables different interactions and sound qualities. It has been an intense experience. Trying to bui ...

Sound Activated Outlet

The Clapper was a popular gadget in the 80's and 90's. It let you turn appliances on and off just by clapping. This can be pretty useful, but it has some limitations. First there is the problem of loud noises accidentally turning the lights off. Also, you can't control multiple outlets independently of each other. So I decided to make programmable version of the Clapper using an Arduino microcontroller. The ...

MEMS sound great, but can it last?

The MEMS (microelectromechanical system) market is starting to motor. It grew at just over 10% last year and is likely to grow even faster this year. This is good news for the ‘newest’ semiconductor device market. But can it continue to grow at this rate? Market analyst Yole Développement has already warned of price pressures pegging back revenue growth over the next few years. According to Yole, price pres ...
