It addresses the issues commonly found in the current market such as large blind zones, wide measurement angles, long response times, and poor installation adaptability for ultrasonic sensors. With a measurement range of up to 3m, it offers advantages such as small blind zones, narrow measurement...
The MB1240 XL-MaxSonar-EZ4 is a high-performance ultrasonic distance sensor with a range of 20 to 765 cm. While this tutorial is written for the MB1240, it can also be used for other MaxBotix sensors, and serves as a great reference for those interested in using an ultrasonic sensor with...
How Does the Arduino Ultrasonic Range Finder Work?For this range finder, we use an UltraSonic sensor to measure the distance between two points. The principle of operation for this sensor is measuring the distance traveled by sound in a given time. The sensor generates high-frequency sound waves...

for i in range (0, 3): 在C 和 Arduino 中,循环如下:for (int i = 0; i < 3; i ++) {... } 这些说法大相径庭。我将在本章后面解释for循环语法。这里要注意的关键是,在 Python 中,i变量是在没有类型的情况下创建的,当第一个值 0 赋给它时,它就变成了一个整数。在 Arduino 中,在给变量...
Serial.print(uS / US_ROUNDTRIP_CM); // Convert ping time to distance in cm and print result (0 = outside set distance range) Serial.println("cm"); lcd.setCursor(0, 0); lcd.print("Distance:"); lcd.setCursor(0, 1); lcd.print(" "); ...
