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 … ...

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.

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 ...

This repository offers a complete document and sample code to use the HC-SR04 ultrasonic sensor with a Raspberry Pi Pico using a C language. It covers sensor pin configuration, wiring and clear ...

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.

Raspberry Pi is offering a 1.6-megapixel global shutter camera module to hobbyists for $50, providing a platform for machine vision, hobbyist shooting and more.

Raspberry Pi has announced a 12.3Mpixel AI camera, based on Sony’s IMX500 intelligent sensor, which “supports on-board processing for a variety of neural network models, leaving the processor in the ...
