Build a simple LPG gas leakage detector using Arduino and MQ-5 sensor. This beginner-friendly project features buzzer and LED alerts, circuit diagram, and complete Arduino code for home safety.

In this comprehensive TMC2209 Arduino tutorial, we'll walk through a complete example of how to interface a Bigtree Tech TMC2209 stepper motor driver with Arduino UNO for precise directional rotation ...

This is generally true because few mixed signal circuits are pad limited. By having a shorter pad, the over all circuit size is smaller which results in a cost savings. Most I/O pads for mixed signal ...

Dalian University of Technology researchers advance flexible circuits using 3D printing - producing freestanding 3D conductive wires.

Tom] has taken a DIY approach to smart sailing with a Raspberry Pi as the back end to the navigation desk on his catamaran, the SeaHorse. Tucked away neatly in a waterproof box with a silicone ...

The image quality of side-scan sonar (SSS) is determined by its operating frequency. SSS operating at a low frequency produces low-quality images due to high levels of noise. This noise is randomly ...

In this brief, we designed, constructed, and analyzed a frequency-tunable metamaterial resonator. The proposed design consists of an S-shaped resonator, a ground frame, and a feeding transmission line ...

How to use a circuit breaker finder to understand your home's wiring (and why it matters so much) I almost paid for new wiring - until this Klein tool showed me the power was already there.
