A new Raspberry Pi project ... GY-91 shematic. Connect sensor through the GPIO. There is a very little manipulation to connect 4 pins of the sensor on the GPIO. 3v3 is for 3.3v power, got to ...

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] built an eight-sensor HC-SR04 breakout board, because the ultrasonic distance ... that’s a Raspberry Pi, so he needed the usual 5 V to 3.3 V level shifting in between.

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 ...
