DIY Programmable 8-step tone sequencer

The people at Beavis Audio Research were experimenting with an Arduino board to create various tones and followed this up by creating a musical sequencer with eight positions. By including controls for duration, frequency, tempo and volume some nostalgic video game sound effects can be created, for example:

 

By taking the time to enclose the project into a neat housing the sequencer has moved from a simple project to a product that can be used by anyone. Which goes to show what can be capable with an Arduino-based project. For more information, including design story code and schematics, visit this page. When building your own embedded-Arduino project, consider using our Freetronics LeoStick – one of the smallest Arduino-compatibles on the market with onboard USB, RGB LED and piezo:
