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 ...

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 ...

DIY robot dogs made possible by Raspberry Pi Pico and cheap SBCs. Cucumber, a pet robot, was successfully created by ...

A Raspberry Pi can be used for a huge range of applications, but we think the most useful might be as a fart detector. Here's how to set one up.

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 ...

Figure 2 Ultrasonic sensors can be used for HVAC and lighting controls to turn heating and cooling equipment and lighting systems on and off using people detection. Source: Shutterstock. A prime ...

We will use a PIR motion detection sensor, and whenever motion is detected, the Raspberry Pi 4 Camera will take a picture and send an email with the picture attached.” Setting Up the Project ...

Home Assistant is the beating heart of my smart home setup. I run it on a Raspberry Pi 5 with a fast M.2 NVMe SSD, and it handles everything from basic light controls to more complex motion-based ...

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 video shows the working principle of the advanced ultrasonic sensors from Physik Instrumente (PI). Developed for flow measurement and bubble detection, the PI ultrasonic sensors are ...

It’s really easy to use a Raspberry Pi to create a cheap surveillance system with just one camera, but things get complicated if you want multiple cameras. Over on Pyimagesearch, they figured ...
