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 ...

More often than not, an IoT master device uses the SPI (serial peripheral interface) and I 2 C (inter-integrated circuit) protocols to exchange data with EEPROMs or sensors that are operating in slave ...

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 ...

Andy Grove has published details of a new Ultrasonic Raspberry Pi Piano he has created which can be played using gestures. This innovative project combines the versatility of the Raspberry Pi mini PC ...

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 ...
