In the “piano” demo, that’s a Raspberry Pi, so he needed the usual 5 V to 3.3 V level shifting in between. The rest is code on the Pi that enables gestures to play notes, change musical ...

This innovative project combines the versatility of the Raspberry Pi mini PC with the precision of HC-SR04 ultrasonic sensors to create a unique musical instrument. Check out the video below to ...

Ultrasonic Distance Monitoring System This project utilizes a Raspberry Pi, an ultrasonic sensor (HC-SR04), and Flask to create a real-time distance monitoring system. The system measures distances, ...

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 ...

As the servo rotates, the returns from the ultrasonic sensor are plotted on a screen run by a Raspberry Pi. If an object is detected in the 180-degree field of view of the sweeping sensor, a ...

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 ...
