“This is a simple distance detection circuit with the use of an ultrasonic sensor, a buzzer, a row of LEDs, and 2 relays (optional). The ultrasonic distance sensor will light a row of LEDs depending on distance. Then if a change in distance is detected, that exceeds your threshold, a buzzer will sound and the optional relays can toggle a device (a light). All options are configurable such as the threshold, number of LEDs, maximum perceived distance, etc…”
