Arduino sensor projects blend coding with tangible results, making learning interactive, practical, and fun. From simple LED triggers to multi-sensor systems, these builds teach real-world electronics ...

The ionosphere is of great importance to shortwave radio transmissions, since it allows radio waves to be refracted and ...

Arduino’s open-source platform makes it easy for makers, students, and hobbyists to build powerful multi-sensor projects for home automation, monitoring, and IoT applications. From motion and gas ...

A very cool (also warm!) property of the base-emitter junction of (most) small signal BJTs is the ΔVbe temperature-sensing ...

May 3, 2026 • The Stillaguamish Tribe in Washington state has been buying land in its traditional territory and removing levees. The goal is to turn farmland into wetlands with the hopes of restoring ...

Abstract: This letter addresses the problem of human activity recognition (HAR) of people wearing inertial sensors using data from the UCI-HAR dataset. We propose a light residual network, which ...

Abstract: Light field imaging is an emerging research field due to the new capabilities it brings, including post-capture refocusing, aperture control, and 3D modeling. Single-shot single-sensor light ...
