The HC-SR04 is an inexpensive, easy to use ultrasonic distance sensor, with a range of 2cm to 400 cm. It is commonly used in obstacle avoiding robots and automation projects. In this tutorial, you will learn how the sensor works and how to use it with Arduino. I have included 5 exampl...
You can upload the example code with the IDE. /* Arduino example code for MaxBotix MB1240 XL-MaxSonar-EZ4 ultrasonic distance sensor: analog voltage output. More info: www.makerguides.com */ #define sensorPin A0 int distance = 0; void setup() { Serial.begin(9600); } void read_sensor(...
1) 利用 Arduino 的数字引脚给超声波传感器的 Trig 引脚至少 10 微秒的高电平信号,这会让HC-SR04 超声波测距模块发射出8个40K赫兹的超声波脉冲(ultrasonic burst)。 2) 8个超声波脉冲发出后,echo引脚会输出高电平。假如没有声波返回,echo引脚会在38微秒后输出低电平。假如有声波返回,echo引脚会进入低电平状态。
A sensor is a device that converts one type of energy to another. Arduino is a small microcontroller board with a USB plug to connect to the computer. The Arduino board senses the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lcds, ...
With Arduino ultrasonic sensors like the HC-SR04, you can measure the distance. Through this Arduino tutorial, you will learn how an Ultrasonic sensor works and how do you use it with the Arduino and even with the Raspberry Pi.
/Firmware - Arduino example code. Make sure to check the pin definitions and what you are connecting to. Documentation Hookup Guide - Basic hookup and project example using the ultrasonic sensor. (Note: The example code used in this tutorial is slightly different than the basic example used ...
instructions and sample code, including support for Arduino image recognition and MQ 8 sensor Arduino code. The module's simple wiring method, with VCC, trig, echo, out, and GND pins, allows for straightforward connection and operation. The module's live imaging transducer capability adds an ...
This project introduces us to the HC-SR04 Ultrasonic Sensor. We will be creating an alarm circuit with a buzzer and warning LEDs. You will understand how an ultrasonic sensor works and how to interact with it in code. This is a very handy addition to your electronics projects for obstacle ...
