Building an automated attendance system using ESP32-CAM is a practical, affordable way to solve this problem for classrooms, ...

If you miss the days when you used Basic on your classic computer or wrote embedded software with a Basic Stamp, then maybe dust off your Arduino UNO or any similar AVR board and try nanoBASIC_UNO ...

In robotics, movements must be precise and well-controlled. As robots are asked to do more as industry becomes more familiar with the technology, there will be an increasing need for high accuracy ...

Daniel Ansorregui has developed LightInk, an open-source solar-powered E-ink watch inspired by 90s solar digital watches. It ...

What's CODE SWITCH? It's the fearless conversations about race that you've been waiting for. Hosted by journalists of color, our podcast tackles the subject of race with empathy and humor. We explore ...
