Processing Code

The document is a Processing sketch that visualizes data from a serial port, specifically displaying angle and distance measurements. It creates a radar-like interface that draws arcs and lines based on the received data, indicating whether an object is in range. The sketch updates in real-time, showing both the angle and distance of detected objects along with corresponding text labels.
