Launched this winter, the Data-Driven Plant Science course bridges experimental biology with embedded sensing, bioinformatics, and machine learning.

The ESP32 is one of the best microcontrollers on the market for building low-power sensors. By connecting a microphone (and sometimes a few additional components), the ESP32 can react to sound in some ...

Nailing the basics.

When a singer belts out a tune while a guitar player strums along, sound waves travel through the air, driving collective oscillations of the molecules within. Meanwhile, at the quantum level, ...

There are plenty of ways to get sound into your house: good old fashioned headphones, the Dolby surround setup we all lusted ...
