This project uses an HC-SR04 ultrasonic sensor, LCD1602 I2C display, and a buzzer to simulate a real-time parking assist system using a Raspberry Pi. 🛠️ Features Measures distance using ultrasonic ...

In the “piano” demo, that’s a Raspberry Pi, so he needed the usual 5 V to 3.3 V level shifting in between. ... HC-SR04, piano, raspberry pi, ultrasonic sensor. Post navigation.

This module uses an ultrasonic sensor to trigger certain notes to be played through the pi. An object is held in front of the sensor and moved either closer or further away to make music. This is ...

In this module we will wire up an ultrasonic sensor and attach it to our Raspberry Pi. Using the ultrasonic sensor we will measure the distance an object is away from the sensor. The distance of the ...

Using a Raspberry Pi mini PC together with inexpensive HC-SR04 ultrasonic sensors as inputs, the system generates MIDI notes which can be played through a synthesizer on the Pi to output high ...

The project is completely open source and based on a Raspberry Pi base station which connects to ESP32 based sensor nodes and online services to nicely present the data on a 7″ touch screen display.
