We propose a method based on the phase diagram tool to evaluate the sparse microwave imaging radar system. In the method, success rates of signal recovery are derived from the statistics of relative ...

Orthogonal frequency-division multiplexing (OFDM) signal coding and system architecture were implemented to achieve radar and data communication functionalities. The resultant system is a ...

A system that uses a PID controller to balance a ball on a tiltable platform. The system is built with an Arduino, ultrasonic sensor, and servo motor, with PID gain tuning via potentiometers. The ...

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.
