This project uses an Arduino microcontroller with an HC-SR04 ultrasonic sensor to measure distances. The Arduino emits ultrasonic pulses and measures the time it takes for the echo to return. This ...

Slave: Measures distance using an ultrasonic sensor and sends the data via I2C. Master: Receives the distance data, stores the last 10 readings in a simulated EEPROM, and can display stored data via ...

Of course, many different types of distance measuring sensors exist but not all sensors are the same. Each sensor has its own advantages and disadvantages. At its most basic level, a distance ...
