EASY plug SR01 Ultrasonic Module

Introduction

The distance sensor are really common in robotics projects, very useful for automation, interactive art and motion sensing.
This EASY Plug SR01 Ultrasonic integrates ultrasonic transmitter, receiver and corresponding control circuit.
It should be connected to the double digital interface with only one line, which is very easy to use and convenient for connection.
The module comes with four fixed holes, so that can easily fix it on other devices, such as the servo plastic platform and so on.
Note: this module should be used together with EASY plug control board.

Connect It Up

Connect the EASY Plug Ultrasonic module to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.

Upload the Code

Below is an example code. Open or drag below code to Mixly Blocks and upload.

What You Should See

Done uploading the code, open the serial monitor and set the baud rate to 9600. You should see the measured distance between the ultrasonic sensor and front obstacle.

Turn on Light

When the measured distance between an obstacle and ultrasonic sensor is less than a certain range, turn the led on.

Hookup Guide

Test Code
Below is an example code. Open or drag below code to Mixly Blocks and upload.

What You Should See
Upload success, when the measured distance is less than 30, the LED will be turned on. Otherwise, the LED is turned off.
