Cheap stuff gets our creative juices flowing. Case in point? [Andy Grove] built an eight-sensor HC-SR04 breakout board, because the ultrasonic distance sensors in question are so affordable that a … ...

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 ...

Raspberry Pi enthusiasts, developers, or makers wishing to connect multiple sensors to their Raspberry Pi mini PC may be interested in the Whitebox Labs T3 shield and Atlas EZO sensors, which when ...

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.

SJEC-AICTE IDEA lab in collaboration with Department of Electronics and Communication Engineering (ECE) at St Joseph ...

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 ...
