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。
After this, I created two functions: read_sensor and print_data. In the read_sensor function, we simply read the analog voltage sensor output with the function analogRead(pin). The Arduino boards contain a multichannel, 10-bit analog to digital converter. This means that it will map the inp...
