Additional Project: Raspberry Pi Ultrasound Sensor. Also, ... can measure distances by emitting ultrasonic waves and calculating the time it takes for the echo to return.

In the “piano” demo, that’s a Raspberry Pi, so he needed the usual 5 V to 3.3 V level shifting in between. ... HC-SR04, piano, raspberry pi, ultrasonic sensor. Post navigation.

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 ...
