Verified summary

Arduino-based educational radio demonstration inspired by uplink/downlink concepts associated with deep-space communication.

Problem or experiment question

How can a classroom-friendly RF demo illustrate uplink and downlink mode switching without claiming realistic DSN protocol behavior?

What was actually built

  • Serial command mode switching between uplink transmit and downlink receive
  • Basic fixed-message transmission with LED feedback
  • Servo sweep representing a dish and 433 MHz RF components

Important technical decisions

  • Fixed messages keep the demo understandable in a classroom setting
  • Servo dish motion provides visual anchoring for link direction
  • 433 MHz components chosen for accessible hardware experimentation

Architecture or workflow

  • Command layer: serial mode selection
  • RF layer: transmit/receive with fixed payload
  • Feedback layer: LEDs and servo dish motion

Known limitations

  • No realistic DSN protocol, telemetry, error correction, or link-budget simulation
  • Fixed payload behavior only
  • Educational demonstration, not aerospace-grade communications
