Arduino Proximity Alarm
https://www.electronics-lab.com/news/arduino-proximity-alarm/
Lucas Reed @ instructables.com has build a proximity alarm using Arduino and an ultrasonic sensor from Parallax. If a nearby object is approaching then the alarm will sound and an RGB LED will light up. He writes: An ultrasonic rangefinder and Arduino microcontroller will check for nearby objects and if need be, alert you with […]
