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
Arduino - Ultrasonic Sensor Arduino - 超声波传感器的实现 Arduino’s pins can generate a 10-microsecond pulse and measure the pulse duration. Therefore, we can get the distance from the ultrasonic sensor by using two Arduino’s pins: Arduino的引脚可以产生10微秒的脉冲并测量脉冲持续时间。因此,我们...
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, speakers, motors and GS module. Ultrasonic Sensor measure the distance ...
