The Sonar:bit is an ultrasonic sensor module that works with 3 or 5 Volts. It can be easily used with only one 3-wire(GVS) cable, saving a wire from the usual 4- wire ultrasonic modules.
The measurement range of sonar:bit is 4cm-400cm. It can output stable and accurate measurement data with only ±1cm tolerance. You can use this module for measuring short distances on smart cars, robots, micro:bit and arduino.
Transmitter is used to send ultrasonic signals.
Receiver is for collecting ultrasonic signals.
This is the master chip for the 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 y
Connect sonar:bit to P2 port on sensor:bit and connect micro:bit to your computer.
Once completed, you can see the picture below:
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: https://makecode.microbit.org/_b7JL2Yd3q3Km
Or you can download it from the page below:
We can see the distance in centimetres, between the sonar:bit and the object displayed on the micro:bit in real time.
