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 ...

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.

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 ...

A lot of the best Raspberry Pi projects are all about connecting and controlling your Raspberry Pi from afar. Particle is a web service that helps make that process a little easier and they’ve ...

' PiLiDAR ' is a project to develop a homemade 360-degree 3D panoramic scanner using the single-board computer Raspberry Pi and a LiDAR sensor, allowing anyone to build a portable 3D scanning ...

The raindrop sensor detects the presence of rain by measuring the conductivity of water droplets on its surface. The setup involves connecting the sensors to the Raspberry Pi’s GPIO pins.

The resulting ‘Raspberry Pi Camera Module 3 Sensor Assembly’ measures 10.8 x 10.8mm plus the connecting flexy. Inside, its die is the 4,608 x 2,592 (11.9Mpixel) Sony IMX708, which has 1.40μm pixels, a ...

A Raspberry Pi-powered sensor can help you detect inaudible sounds from your surrounding area.
