Four ultrasonic sensors around an Arduino Nano that sound buzzer alerts when obstacles come close. We designed the circuit and built it on perfboard.
The circuit was laid out in Fritzing first, then built and soldered on perfboard. An Arduino Nano polls four HC-SR04 ultrasonic sensors and drives buzzers as objects approach, giving all-round proximity warnings for mobility aids, vehicles or machinery.
