Description

Sonar:bit is an ultrasonic module with 3-5V working voltage. It is available to be used to 3.3V or 5V micro-controller system. With only one 3-wire(GVS) cable, it can work properly. Compared to the normal 4-wire ultrasonic module, it has saved one IO port. The measurement range of sonar:bit is 4cm-400cm. It can output stable and accurate measurement data with ±1cm tolerance only. You can use this module to occasions like short-distance measurement, smart cars, robots, micro:bit and arduino teaching, etc..

Features

Input voltage:3V~5V

Enable to drive micro:bit or arduino directly.

Standard 3-wire GVS connecotr, which occupies 1 IO port only.

 Definition of Pins

Introduction of Major Components

Transmitter

Transmitter is used to send ultrasonic signals.

Receiver

Receiver is for collecting ultrasonic signals.

MCU

This is the master chip of sonar:bit.

Chip for Sending Signal

This chip is used to drive the transmitter to send out ultrasonic signals.

Chip for Receiving Signal

This chip is used to receive and process ultrasonic echo signals as well as give feedbacks to the master chip.

G-V-S Port

G-V-S port allows outer devices control.

Quick Start

Hardware Connection

Connect sonar:bit to P2 port on sensor:bit and connect micro:bit to your computer.

Once completed, you can see the picture below:

Programming

Click to open Makecode online editor.

Write your program to assign the returned value of P2 to variable distance and display it on micro:bit screen.

You can see the whole program from the link here

Result

We can see the distance between sonar:bit and the object is displayed on micro:bit in real time. The unit is centimeter.
