If you are interested in embedded systems and sensor-based projects, building a DIY Radar Simulation using Arduino, Ultrasonic Sensor, and Servo Motor is a perfect project to begin with. It combines concepts of electronics, coding, and simulation, while also giving a clear visualization through Processing IDE (for the graphical radar interface) and Proteus simulator (for hardware verification). 📡 Project Overview This radar simulation mimics how real radars detect objects by sending signals and measuring reflections. An Ultrasonic Sensor (HC-SR04) sends out sound pulses and waits for their echo to return. The Arduino Uno calculates the time taken for the echo and converts it to distance . A Servo Motor rotates the ultrasonic sensor between 15° to 165° , scanning the environment. The Arduino sends angle and distance data over the Serial Port . The Pro...
