I thought it must be possible to make a warning system in this time with Covid19. I used already some time to understand the Arduino computer. In the past I bought a Freeduino. I am already busy to automate and control a model Tug, named "IONIA". The BlueTooth control is already operating.

So I Looked at the samples with the Arduino computers and mixed a number of applications to construct The WarningWarning system

EXPANDED TECHNICAL DETAILS

Voice-Synthesized Proximity Sentry

This advanced safety project uses an Arduino Pro Mini to provide audible "Voice Warnings" when an object gets too close, making it ideal for blind-spot detection or social distancing aids.

  • WAV-Playback Audio Kernel: Uses the TMRpcm library to play pre-recorded high-quality WAV files from a micro-SD card. The Arduino (Pro Mini) can output "Warning! Object Detected" through a small speaker via a filtered PWM pin.
  • Sub-Centimeter Distance Analytics: Manages an HC-SR04 sensor. The firmware calculates the distance and triggers different voice files based on the range (e.g., "Step Back" at 1m, "Stop!" at 30cm).

Prototyping

  • Verified with Arduino IDE: Optimized for 100% stable performance and zero audio jitter, even with the compact memory footprint of the Pro Mini.
