Monitoring heart rate is essential for athletes, researchers, and hobbyists, yet calculating it manually can be error‑prone. The Pulse Sensor—a plug‑and‑play optical sensor—provides a quick, reliable way to capture heartbeat data. Designed primarily for Arduino, it’s ideal for students, developers,

In oil and gas subsea production systems, a subsea “Christmas tree” is mounted on the wellheads. Each tree controls the oil and gas production of its respective well via multiple process valves. Each process valve is actuated by a subsea valve actuator (SVA) that must be able to safely close the val

An LDR, or light‑dependent resistor, is a low‑cost, photosensitive component commonly found in light meters, flame detectors, and automatic lighting systems. Its resistance drops dramatically when illuminated, making it ideal for a wide range of sensor applications. Engineering‑Grade LDR Projects Ha

Parking is a core skill for every driver, yet it can become a challenge—especially for newcomers or when space is limited. Traditional methods rely on mirrors and judgment, which can result in minor bumps or even larger collisions. Modern vehicles counteract these risks with parking sensors that del
