Sonar:bit is an ultrasonic module with 3-5V voltage range. It can be used with 3.3V or 5V micro-controller systems only requiring a single 3-wire(GVS) cable. Compared to normal 4-wire ultrasonic modules, this saves one IO port.
The measurement range of sonar:bit is 4 cm-400 cm (1.57″ – 157.48″) . It can output stable and accurate measurement data with ±1 cm (0.39″) tolerance. You can use this module for short-distance measurement, smart cars, robots, micro:bit and Arduino instruction, Raspberry Pi, etc.
Features
- Input voltage:3V~5V
- Enable to drive micro:bit or Arduino directly.
- Standard 3-wire GVS connector, which occupies 1 I/O 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 feedback to the master chip.
G-V-S Port
G-V-S port allows external device control.
Quick Start
Hardware Connection
Connect sonar:bit to P2 port on sensor:bit and connect micro:bit to your computer.
Programming
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: https://makecode.microbit.org/_b7JL2Yd3q3Km
We can see the distance between sonar:bit and the object is displayed on micro:bit in real time. The units are in centimeters.
