HC-SR04 Ultrasonic Distance Sensor library for Arduino

calculate the distance of the object with sensor and display to 16x2 LCD with arduino

The main objective of this project is to help blind people to walk with ease and to be warned whenever their walking path is obstructed with obstacles. As a warning signal via buzzer, whose frequency of beep changes according to the distance of the object.

Measurement circuit for object distance in low light conditions.

ultrasonic distance sensor arduino

📏Make a digital ruler using an Arduino Uno, a four seven-segment display, and a HC-SR04 sensor.

By using the Sonar sensor (ultrasonic sensor), turn on the alarms when it detects object less than certain ranges. This can approach to the parking assist.
