Distance_Alarm_v3.1

Automatic Distance Alarm System - Lite

This is pre-release because for some reason the wifi access point doesn't properly respond to inputs from clients.

• Uses the ESPRESSIF ESP32S2 microcontroller, code written in Arduino IDE in C++
• Computes distance from an ultrasonic distance sensor and speed of sound algorithm
• Activates alarm function if distance < threshold, or button is held down
• Alarm is alternating flashing lights plus a loud buzzer
• Buzzer can be silenced through website hosted on its wireless access point
• Distance and more feedback info is available in the serial monitor (terminal-like window) of the Arduino IDE
• Distance & more feedback also now available on the 4-digit display
